High specific surface CeO-NPs doped loose porous CNfor enhanced photocatalytic oxidation ability.

Porous CN(PCN) is favored by researchers because it has more surface active sites, higher specific surface area and stronger light absorption ability than traditional g-CN. In this study, cerium dioxide nanoparticles (CeO-NPs) with mixed valence state of Ceand Cewere doped into the PCN framework by a two-step method. The results indicate that CeO-NPs are highly dispersed in the PCN framework, which leads to a narrower band gap, a wider range of the light response and an improved the separation efficiency of photogenerated charge in PCN.

Synthesis of coralloid carbon nitride polymers and photocatalytic selective oxidation of benzyl alcohol.

Polymeric carbon nitride (CN) is currently the most potential nonmetallic photocatalyst, but it suffers from low catalytic activity due to rapid electron-hole recombination behavior and low specific surface area. The morphology control of CNis one of the effective methods used to achieve higher photocatalytic performance. Here, bulk, lamellar and coralloid CNwere synthesized using different chemical methods.

Catalytic developments in the epoxidation of vegetable oils and the analysis methods of epoxidized products.

Functionalization of vegetable oils (VOs) including edible, non-edible, and waste cooking oil (WCOs) to epoxides (EVOs) is receiving great attention by many researchers from academia and industry because they are renewable, versatile, sustainable, non-toxic, and eco-friendly, and they can partially or totally replace harmful phthalate plasticizers. The epoxidation of VOs on an industrial scale has already been developed by the homogeneous catalytic system using peracids. Due to the drawbacks of this method, other systems including acidic ion exchange resins, polyoxometalates, and enzymes are becoming alternative catalysts for the epoxidation reaction.
