Single-atom (SA) catalysts exhibit high activity in various reactions because there are no inactive internal atoms. Accordingly, SA cocatalysts also an active research fields regarding photocatalytic hydrogen (H2) evolution which can be generated by abundant water and sunlight. Herein, it is investigated whether 10 transition metal elements work as on graphitic carbon nitride (g-C3N4; i.e., gCN...
Photocatalysis delivers a promising pathway toward the clean and sustainable energy supply of future. However, inefficiency photon absorption, rapid recombination photogenerated electron-hole pairs, especially limited active sites for catalytic reactions result in unsatisfactory performances photocatalytic materials. Single-atom photocatalysts (SAPCs), which metal atoms are individually isolate...
The chromium/vanadium bimetallic Phillips catalysts developed by our research group have been proved to be a promising process to produce bimodal polyethylene using a single-reactor process. The vanadium loading of CrV-1/1, CrV-1/2, and CrV-1/3 has a significant effect on the polymerization activity, product molecular weight (MW), as well as th...
Photocatalytic removal of single volatile organic compounds (VOCs) has been widely investigated; however, photodecomposition VOC mixtures rarely addressed, which may bring safety doubts in indoor air purification due to possible formation harmful compounds. Here we show that photocatalytic oxidation formaldehyde–toluene and formaldehyde–xylene mixtures, the introduction Pd cocatalyst on TiO2 ph...
