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...

Cobalt oxides, CoO and Co3O4, were obtained from Co (II) acetate tetrahydrate. The thermal decomposition pathway of the starting product was followed by combining thermogravimetric analysis in situ X-ray thermodiffraction. Under a nitrogen atmosphere, cobalt monoxide with Zn-blende rocksalt polymorphs could be almost as single phases at 330 400 °C, respectively. In addition to these oxyacetate,...

Co3O4, MgCo2O4 and MgO materials have been synthesized using a simple co-precipitation approach systematically characterized. The total conversion of toluene to CO2 H2O over spinel with wormlike morphology has investigated. Compared single metal oxides (Co3O4 MgO), the highest activity exhibited almost 100% oxidation at 255 °C. obtained results are analogous typical precious supported catalysts...

Effects of supports (Co3O4, CeO2, NiO) in the gold-catalyzed aqueous phase oxidation ethanol (EtOH) to acetic acid (AcOH) were examined. ATR-IR spectroscopy under working conditions catalysts uncovered on gold particles bidentate ethoxy, and monodentate ethoxy species, multi-layered ethanol, acetate. Preferential formation species adsorbed EtOH identified as key factors for high activity select...
