Selective photoelectrochemical oxidation of glycerol to high value-added dihydroxyacetone
Nature Communications, 2019 It is highly profitable to transform glycerol – the main by-product from biodiesel production to high value-added chemicals. In this work, we develop a photoelectrochemical system based on nanoporous BiVO4 for selective oxidation of glycerol to 1,3 ...

Advanced Science, EarlyView.This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

Polarons in Heterogeneous Photo(electro)Catalysts
Angewandte Chemie, EarlyView.Polarons are defined as quasiparticles consisting of electrons/holes covered by a cloud of virtual phonons, which are beneficial/detrimental to the electronic properties of materials. This minireview provides a conceptual overview of how small polaron formation influences the photon absorption, charge transport and separation, and surface reactivity in

Advanced Science, EarlyView.A polymer‐intercalated modulation assembly strategy was proposed to synthesize mesoporous single‐crystalline BiVO4 with tunable pore structure by co‐assembly of inorganic–organic composite through coordination bonds and hydrogen bonds. Thanks to single‐crystalline properties and mesoporous structure with vanadium vacancy microenvironment, the prepared ...

Advanced Science, EarlyView.Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.
