Abstract The utilization of compounds from natural sources to prepare functional materials is great importance. Herein, we describe for the first time preparation organic–inorganic hybrid catalysts by using phytic acid as building block. Zirconium phosphonate (Zr‐PhyA) was synthesized reaction and ZrCl 4 obtained a mesoporous material with pore sizes centered around 8.5 nm. Zr‐PhyA used catalyze mild selective Meerwein–Ponndorf–Verley (MPV) reduction various carbonyl compounds, e.g.,...
The effect of water on CO2 hydrogenation to produce higher alcohols (C2-C4) was studied. Pt/Co3O4, which had not been used previously for this reaction, applied as the heterogeneous catalyst. It found that and catalyst an excellent synergistic promoting reaction. High selectivity C2-C4 could be achieved at 140 °C (especially with DMI (1,3-dimethyl-2-imidazolidinone) co-solvent), is a much lower temperature than reported previously. reused least five times without reducing activity...
Abstract Benzene is a widely used commodity chemical, which currently produced from fossil resources. Lignin, waste lignocellulosic biomass industry, the most abundant renewable source of benzene ring in nature. Efficient production lignin, requires total transformation C sp2 -C sp3 /C -O into C-H bonds without side hydrogenation, great importance, but has not been realized. Here, we report that high-silica HY zeolite supported RuW alloy catalyst enables situ refining exclusively to via...
Proton-exchange membrane fuel cells (PEMFCs) are limited by their extreme sensitivity to trace-level CO impurities, thus setting a strict requirement for H2 purity and excluding the possibility directly use cheap crude hydrogen as fuel. Herein, we report proof-of-concept study, in which novel catalyst comprising both Ir particles single-atom sites (IrNP @IrSA -N-C) addresses poisoning issue. The found not only be good oxidizing sites, but also excel scavenging molecules adsorbed on close...
Cyclohexanols are widely used chemicals, which mainly produced by oxidation of fossil feedstocks. Selective hydrodeoxygenation lignin derivatives has great potential for producing these chemicals but is challenging to obtain high yields. Here, we report that CeO2-supported Ru single-atom catalysts (SACs) enabled the hydrogenation benzene ring and catalyzed etheric C-O(R) bond cleavage without changing C-O(H) bond, could afford 99.9% yields cyclohexanols. As far as know, this first SACs...

Splitting HCOOH (FA) into H2 and CO2 with high turnover frequencies selectivity is highly desirable for generation its facilitated utilization. However, the mostly adopted Pd based metallic catalysts severely suffered from low catalytic efficiency self-poisoning, owning to FA dehydration side reaction. Here, we demonstrate first that secret developing active selective toward FAD lies in building abundant Pd–PdO interfaces at surface. Using a chemical blocking technique, identify surface...
