Sulfur-doped graphitic carbon nitride incorporated bismuth oxychloride/Cobalt based type-II heterojunction as a highly stable material for photoelectrochemical water splitting

Electrochemical Reduction of CO2: A Review of Cobalt Based Catalysts for Carbon Dioxide Conversion to Fuels

“…Cobalt nitrides have proved beneficial for CO 2 RR because they offer more surface base sites of adsorption of CO 2 and the generation of more active sites [ 140 , 141 , 142 , 143 , 144 , 145 , 146 ]. Peng et al reported the highly efficient CO 2 RR cobalt nitride catalysts (700-Co 5.47 N/C) in an aqueous electrolyte.…”

Synthesis, Functional Modifications, and Diversified Applications of Hybrid BiOCl-Based Heterogeneous Photocatalysts: A Review

“…The above factors seriously inhibit the application of bare BiOCl in photocatalysis. Currently, it has been proven that the construction of BiOCl-based heterostructures is an effective strategy for enhancing photocatalytic performances. − …”

“…Enormous efforts have confirmed that heterojunction engineering, element doping, defect engineering, and morphology and crystal facet engineering are the prominent strategies for enhanced photocatalytic activity. − Among these modification methods, heterojunction engineering can not only improve the active sites and solar light absorption of photocatalyst but also promote the spatial separation of photocharge carriers. − On the basis of the above consideration, a large number of BiOCl-based heterogeneous photocatalysts with enhanced performances have been constructed. − Currently, they are widely applied in degradation of organic pollutants including rhodamine (RhB), methyl orange (MO), methyl blue (MB), tetracycline hydrochloride (TC-HCl), tetracycline (TC), ciprofloxacin (CIP), and imidacloprid, as well as in the detection of heavy metal ions such as Cd­(II) and Pd­(II). − However, applications in other areas such as water splitting hydrogen production, NO removal, CO 2 reduction, disinfection, and the oxidation of alcohol are rare. ,,− Consequently, the current investigations on microstructures and photocatalytic performances of various BiOCl-based heterostructures are mainly based on the photocatalytic degradation of organic pollutants for understanding their enhanced photocatalytic mechanisms. As for a metal/BiOCl system, the formation of a Schottky barrier at the interface of metal/BiOCl and the plasmonic effect of metal species jointly boost the improvement of its photocatalytic activity.…”

Construction of a double heterojunction between graphite carbon nitride and anatase TiO2 with co-exposed (101) and (001) faces for enhanced photocatalytic degradation

“…In order to compound the two particles in different morphologies, various compounding methods have been tried by previous authors. 22,23 According to the literature, g-C 3 N 4 /TiO 2 photocatalysts have been synthesized by hydrothermal reaction method, sol-gel method, and so template synthesis method, etc [24][25][26] .…”
