A generalized hydrothermal strategy for fabricating three-dimensional (3D) battery electrodes is presented. The hydrothermal growth deposits electrochemically active nanomaterials uniformly throughout the complex 3D mesostructure of the scaffold. Ni inverse opals coated with SnO2 nanoparticles or Co3O4 nanoplatelets, and SiO2 inverse opals coated with Fe3O4 are fabricated, all of which show att...

Cubic ordered mesoporous Co3O4, prepared via the nanocasting pathway using KIT-6 as hard template, was found to be an excellent catalyst for low temperature CO oxidation, with the activity clearly depending on surface area and pore systems of the catalysts.

A facile in situ vapour phase hydrothermal (VPH) surface doping approach has been developed for fabrication of high performance S-doped Co3O4 electrocatalysts with an unprecedentedly high surface S content (>47%). The demonstrated VPH doping approach could be useful for enrichment of surface active sites for other metal oxide electrocatalysts.

Herein, we introduce a specially designed domain-confined macroporous catalyst, namely, the Co3O4 nanocrystals anchored on a TiO2 nanotube array catalyst, which was synthesized by using the mercaptoacetic acid induced surface-grafting method. This catalyst exhibits much better performance for catalytic soot combustion than the conventional TiO2 powder supported one in gravitational contact mode...

The ever-increasing quantity of spent lithium-ion batteries (LIBs) is both a potential environmental pollutant and valuable resource. LIBs recycling mainly aimed at the separation elements. Some issues still exist in these processes such as high energy consumption complex procedures. This study avoided element proposed facile approach to transform LiCoO2 electrode into lithium (Li)-doped graphi...

The catalytic degradation of chlorinated volatile organic compounds (CVOCs) at low temperatures is a great challenge. In this work, Pt-Co/HZSM-5 ternary catalysts were synthesized and used for the oxidation dichloromethane (DCM). By adding only trace amounts Pt (0.01 wt. %), catalyst exhibits better CO2 yield lower by-product than Co/HZSM-5 catalyst. Besides, it maintained stable activity least...

Solving high electrical-energy input for pollutants degradation is one of the core requirements practical application photoelectrocatalytic (PEC) technology. Herein, we developed a self-driven dual-photoelectrode PEC system (TiO2 NNs-Co3O4) composed TiO2 nanoneedle arrays NNs) photoanode and Co3O4 photocathode first time. Under light-emitting-diode (LED) illumination, bias-free NNs-Co3O4 exhibi...

Active granule (WC/Co3O4) doping Ti/Sb-SnO2/PbO2 electrodes were successfully synthesized by composite electrodeposition. The as-prepared systematically characterized scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), diffraction (XRD), photoelectron (XPS), electrochemical performance, zeta potential, and accelerated lifetime. It was found that the of active granule...
