Lignocellulose is a major source of bioenergy. The use of bio-based fuels and materials can reduce environmental emissions and also help improve the economy. To date, there have been fewer commercial applications of lignin obtained from biomass; currently, researchers are working to increase its added value globally. Among the commercial products converted to lignin, there are only a few phenolic compounds, such as ferulic acid (318 tons/year), vanillin (3000 tons/year), etc. Naphthenic hydrocarbons are key precursors in the production of nylon. Naphthanes can be mixed with conventional gasoline and have the following advantages: increased density and volumetric heating, reduced NOx emissions, and reduced particulate matter. In addition, cyclohexane is a potential solvent for extensive organic conversion and azeotropic distillation. In the current situation, the conversion of lignin to naphthenics is one of the most promising value-added options.

In the 21st century, air transportation industry develops rapidly and plays an important role in economic development and national security. Therefore, a safe and stable supply of high-quality aviation fuel is of Paramount importance. Jet fuel is heavier than gasoline and lighter than diesel, and generally contains hydrocarbons with 8-16 carbon atoms. Conventional aviation fuel consists of 20% straight-chain alkanes, 40% branched alkanes, 20% cycloalkanes and 20% aromatic hydrocarbons by volume, and its production mainly depends on non-renewable fossil energy. However, with the exhaustion of fossil energy and the environmental pollution caused by its emissions, people urgently need to find renewable clean fuels to replace or supplement the traditional fossil energy. Biomass is the only renewable resource that can provide liquid biofuel. Compared with traditional petroleum-based jet fuel, bio-jet fuel has a great advantage in that its CO2 emissions are neutral during its life cycle, which can significantly reduce greenhouse gas emissions. The structure and properties of lignin make it have natural advantages in the preparation of cyclic hydrocarbon compounds. If the C-O and C-C bonds in the structure can be selectively broken, lignin can be effectively degraded into monomers or small dimer molecules containing one or two benzene rings, and further converted into aviation fuel with appropriate carbon number (C8-C16) through catalytic hydrodeoxidation.

Transition metal oxides such as ReOx, MoOx and WOx show good activity in the hydrodeoxidation reaction of lignin and its model compounds, which can effectively crack the C-O bond and retain the aromatic ring structure completely in the process of hydrohydrolysis reaction. Among them, it was found that partial reduction of molybdenum oxide would occur during the reaction process and more acid sites would be generated and oxygen vacancies would promote the hydrolyzing reaction. At present, MoO3 catalyst is mainly modified by doping metals with excellent hydrogenation activity, such as Ni, Pt and Co, to improve its catalytic activity through metal-oxide synergism. However, this method often changes the selectivity of the catalyst, which easily leads to complete deoxidation of the product into aromatics or cycloalkane compounds. In order to selectively break c-O bonds in lignin structure to prepare monophenol compounds, the design and synthesis of molybdenum oxide catalyst with more acidity and oxygen vacancy is the key to improve the intrinsic hydrodeoxidation activity.

In the past decade, the consumption of fossil fuels has increased sharply, and the conversion of renewable biomass into chemicals and fuels has attracted more and more attention. Catalytic hydrodeoxygenation (HDO) of lignin has always been a research hotspot, and vacancy engineering is a new way to develop efficient catalysts. Oxygen vacancy and sulfur vacancy are widely used in heteropoly acids. Oxygen vacancies were first proposed in the 1860s. Researchers found that oxygen vacancies can be used as reaction sites to change the structure of materials and the electronic and chemical properties of surfaces. Recently, metal oxides have been proved to be effective HDO catalysts due to their redox properties. The catalytic activity of MoO3, which is excellent in the catalysis of lignin model compounds, depends on the surface coordination unsaturated Mo site (oxygen vacancy). As another anion vacancy, sulfur vacancy is widely used in two-dimensional material MoS2. It can improve the disadvantages of low density of MoS2 active sites and inert substrate, so as to improve the catalytic performance. Traditional MoS2 catalysts usually add second Metals Co and Ni, which can reduce the binding energy of sulfur at the edge of MoS2 and increase the vacancy concentration, so as to improve the performance of the catalyst.

Volatile organic compounds (VOCs), as precursors of ozone and photochemical smog, not only cause many environmental problems, but also endanger human health. Catalytic oxidation is one of the most potential treatment technologies. The development of efficient and stable monolithic catalysts is of great significance for the removal of volatile organic compounds. Recently, non noble metal oxides derived from metal organic frameworks (MOFs) show excellent catalytic properties, but their preparation process is prone to agglomeration, resulting in reduced activity. In addition, the support also affects the performance of the catalyst. Copper foam has attracted wide attention in various catalyst carriers due to its three-dimensional channel and good thermal conductivity. However, the lower surface area of foam copper is not conducive to the dispersion of active substances, which reduces the generation of multiphase interface between copper oxide and active substances, and limits the further improvement of the overall catalyst performance.

On December 31, 2021, the "carbon neutralization special committee of Tianjin renewable energy society" (hereinafter referred to as carbon neutralization special committee) led by Professor Song Chunfeng of our group successfully held the 2021 annual committee meeting.

As a natural phenolic polymer with huge reserves in nature, lignin is a very important and abundant renewable resource, which has a very wide application prospect in the field of chemical synthesis. Organic nitrogenous chemicals are a class of chemical products that stimulate the development of modern human society. Their traditional synthesis process relies almost entirely on non-renewable fossil resources, thus exacerbating the potential negative impacts of global climate and environment. With the continuous development of bio-resource value-added technologies in recent years, biomass-based value-added chemicals and alkane fuels can be easily obtained. In particular, based on the special structure of biomass, the catalytic synthesis of organic nitrogen chemicals using biomass resources instead of fossil resources has gradually become a new research focus and has been paid attention to.

At present, diesel particulate filter (DPF) is becoming an essential part of the engine exhaust system under the increasingly stringent emission regulations in terms of particulate quality and quantity control. However, the use of DPF also accelerates the increased flow resistance due to particle collection. In order to avoid the formation of high back pressure in the exhaust pipe, the accumulated particles must be removed regularly or continuously. Soot oxidation reactivity is an important property, which directly determines the regeneration process of DPF.
