Fluidized Bed Chemical Vapor Deposition on Hard Carbon Powders to Produce Composite Energy Materials

“…The combination of cheap, environmentally friendly carbon-based materials and inorganic materials with controllable catalytic, electronic, and optical properties is a winning strategy to fabricate versatile materials for energy applications. , Carbon materials are common substrates for the fabrication of heterogeneous catalysts, as by surface modification they can stabilize nanoparticles and achieve tunable catalyst–support interactions . Carbon-supported semiconductors are key materials for advanced photoelectrocatalysis, with important implications in the removal of pollutants from water and for energy conversion applications . In these composites, the formation of a heterojunction can greatly enhance electron–hole pair separation and promote electron transfer over recombination mechanisms.…”

“… 3 Carbon-supported semiconductors are key materials for advanced photoelectrocatalysis, with important implications in the removal of pollutants from water and for energy conversion applications. 4 In these composites, the formation of a heterojunction can greatly enhance electron–hole pair separation and promote electron transfer over recombination mechanisms. Carbon composites are also of great interest for battery electrodes, as highly conductive supports with a large surface-to-volume ratio on which other active materials can be deposited, while the carbon itself can also provide capacity.…”

Highly efficient photoelectrocatalytic oxidation of arsenic(iii) with a polyoxometalate-thiacalix[4]arene-based metal–organic complex-modified bismuth vanadate photoanode

“…18,19 In this facet, photoelectrocatalysis with the combination of photocatalysis and electrocatalysis is one of the promising techniques for the removal of harmful pollutants, and usually possesses a higher conversion efficiency than the traditional photocatalysis or electrocatalysis method. [20][21][22] Due to the synergistic effect between electrocatalysis and photocatalysis, the photoelectrocatalytic system possesses some merits, including environmental friendliness, low energy consumption, easy recovery and sustainability. 23,24 Thus far, numerous photoactive semiconductors, such as ZnO, TiO 2 , Fe 2 O 3 , BiVO 4 (BVO) and WO 3 , have been used as photoelectrocatalysts, owing to their abundant availability, high cost-effectiveness, and photoelectrocatalytic durability.…”
