A Co-MOF-derived flower-like CoS@S,N-doped carbon matrix for highly efficient overall water splitting.

In this study, we constructed a highly effective, low-cost, non-noble-metal-based electrocatalyst to replace Pt catalysts, with a CoS@SNC catalyst being successfully synthesized. The obtained nanocatalyst was characterized scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electron microscopy, powder X-ray diffraction studies, and X-ray photoelectron spectroscopy. Herein, an initially prepared N-containing Co MOF formed flower-like particles, which were obtained a solvothermal method; further it was used for a sulfuration process as a template to achieve an S,N (heteroatom)-doped carbon electrocatalyst with embedded CoS (CoS@SNC).

Efficient photocatalytic degradation of dyes using photo-deposited Ag nanoparticles on ZnO structures: simple morphological control of ZnO.

In this work, morphology-controlled ZnO structures were prepared a hydrothermal method by simple adjustments in the NaOH concentration. The NaOH concentration variation from 0.2 to 1.

A highly efficient nano-sized CuO/SiO egg-shell catalyst for C-C coupling reactions.

Mesoporous SiO-supported CuO nanoparticles as an egg-shell type catalyst were prepared by impregnation method. The obtained CuO/SiO egg-shell nanocatalyst had a large surface area and narrow pore size distribution. In addition, most of the CuO nanoparticles, with sizes around 2.
