Ni2+-assisted catalytic one-step synthesis of Bi/BiOCl/Bi2O2CO3 heterojunction with enhanced photocatalytic activity under visible light

Bi2O2CO3/Bi2O3 Z-scheme photocatalyst with oxygen vacancies and Bi for enhanced visible-light photocatalytic degradation of tetracycline

“…It might be explained by the presence of some nutrient elements in the degraded solution, which might promote the growth of seedlings. 60 The results showed reduced toxicity of the degradation products of tetracycline.…”

Nanostructured NiCo2O4/BiVO4 Heterojunctions for Visible-Light Photocatalytic H2O-to-H2O2 Synchronized Organic Pollutant Oxidation

“…Photocatalysts with desired band gap energy can effectively harvest sunlight with a decrease of electron and hole (e – –h + ) pair recombination rate to enhance photocatalysis reactions. − High reactive species (HRS) such as hydroxyl ( • OH), hydroperoxyl ( • O 2 H – ), and superoxide ( • O 2 – ) radicals could be formed during photocatalysis for oxidation of organic wastewater. , A superoxide radical is an important intermediate for photocatalytic H 2 O 2 generation that may form HRS (such as • OH and • O 2 H – radicals) for oxidation of organic pollutants in wastewater …”

In Situ Hydrothermal Synthesis of Metallic Bi Self‐Deposited Bi2SiO5 with Enhanced Photocatalytic CO2 Reduction Performance

“…Nevertheless, the over‐expenditure and great demands of these precious metals will vastly inhibit their practical applications. [ 25,26 ] Recently, the self‐deposition of non‐noble metallic Bi on the surfaces of Bi‐based catalysts (such as BiOCl, [ 27 ] Bi 4 O 5 I 2 , [ 28 ] and Bi 2 MoO 6 [ 29 ] ) has been considered an simple and effective route for improving light absorption ability and the separation efficiency of photogenerated carriers and, [ 30,31 ] but the in situ growth synthesis and large‐scale production mechanism of metallic Bi self‐modified Bi‐based semiconductors are still unclear.…”
