The sustainable production of succinic anhydride from renewable biomass.

The selective production of C4 bulk chemicals from biomass is significant to replace the traditional method from petroleum resource. In this work, the succinic anhydride (SAN) is directly prepared from bio-based furanic platform compounds utilizing the visible light-induced oxygenation process, in which -tetraphenyl porphyrin (HTPP) and molecular oxygen was employed as the photocatalyst and terminal oxidant, respectively. Under optimal conditions, a 99.

Novel triphenylamine donors with carbazole moieties for organic sensitizers toward cobalt(II/III) redox mediators.

A series of D-π-A organic dyes, X72-75, containing novel triarylamine electron donors have been synthesized for dye-sensitized solar cells (DSCs). The superiority of the asymmetric design of the triphenylamine electron donor over the symmetrical triphenylamine when applied in organic dyes for cobalt cells has been observed. Using X72 with the cobalt(II/III) redox shuttle resulted in an overall power conversion efficiency (PCE) of 9.

Tin-catalyzed efficient conversion of carbohydrates for the production of 5-hydroxymethylfurfural in the presence of quaternary ammonium salts.

An efficient and tin-catalyzed production of 5-hydroxymethyl furfural (5-HMF) from carbohydrates is reported.

A bifunctionalized dye-sensitized TiO(2) film for efficient degradation of methyl orange under visible light irradiation.

A new bifunctionalized TiO(2) film containing a dye-sensitized region and a degradation region was described. A similar structure of dye-sensitized solar cell (DSSC) was fabricated in the dye-sensitized region to accomplish separation of electrons from positive charges, and separation of dye from pollutants to avoid dye decomposition. The bifunctionalized TiO(2) film electrode and anode electrode can degrade methyl orange (MO) in reactors A and B, respectively.
