“…Regardless of the type, AC acts as a catalyst during the removal of diatrizoate. Gamma radiations based AC is more efficient in a way that it has a higher proportion of C atoms International Journal of Photoenergy 9 and contains sp 2 hybridized [224]. With more than 53% of synergistic effect in diatrizoate in the first minute of reaction, commercial carbon is produced from the ultraviolet/AC system [222,223].…”

“…System. In future, it anticipated that the coming photocatalyst generation would have improved internal efficiency regarding separation and also would be placed in contact with molecules of external pollutants [222][223][224]. So to improve the photocatalytic efficiency and separating catalyst from aqueous solution, the hybrid photocatalyst was designed by not moving the metal oxides having a large surface area, to condense pollutants which are diluted [233,234].…”

This review highlighted the developments of safe, effective, economic, and environmental friendly catalytic technologies to transform lignocellulosic biomass into the activated carbon (AC). In the photocatalysis applications, this AC can further be used as a support material. The limits of AC productions raised by energy assumption and product selectivity have been uplifted to develop sustainable carbon of the synthesis process, where catalytic conversion is accounted. The catalytic treatment corresponding to mild condition provided a bulk, mesoporous, and nanostructure AC materials. These characteristics of AC materials are necessary for the low energy and efficient photocatalytic system. Due to the excellent oxidizing characteristics, cheapness, and long-term stability, semiconductor materials have been used immensely in photocatalytic reactors. However, in practical, such conductors lead to problems with the separation steps and loss of photocatalytic activity. Therefore, proper attention has been given to develop supported semiconductor catalysts and certain matrixes of carbon materials such as carbon nanotubes, carbon microspheres, carbon nanofibers, carbon black, and activated carbons have been recently considered and reported. AC has been reported as a potential support in photocatalytic systems because it improves the transfer rate of the interface charge and lowers the recombination rate of holes and electrons.

“…OER has a more crucial issue that strongly relates to stability and efficiency problems due to multielectron oxidation and co-existing thermodynamically easy path of photoanode etching. However, OER in an aqueous medium was validated with organic polymer catalysts/electrolyte solution junctions, obtaining photocurrent densities in the range of a few microamperes [203][204][205], or more bias potential [206]. Saline oxidation is one of the smart systems as alternative oxidation of chloride ions [207,208].…”

Visible-light-driven photoelectrochemical (PEC) and photocatalytic water splitting systems featuring heterogeneous semiconductor photocatalysts (oxynitrides, oxysulfides, organophotocatalysts) signify an environmentally friendly and promising approach for the manufacturing of renewable hydrogen fuel. Semiconducting electrode materials as the main constituents in the PEC water splitting system have substantial effects on the device’s solar-to-hydrogen (STH) conversion efficiency. Given the complication of the photocatalysis and photoelectrolysis methods, it is indispensable to include the different electrocatalytic materials for advancing visible-light-driven water splitting, considered a difficult challenge. Heterogeneous semiconductor-based materials with narrower bandgaps (2.5 to 1.9 eV), equivalent to the theoretical STH efficiencies ranging from 9.3% to 20.9%, are recognized as new types of photoabsorbents to engage as photoelectrodes for PEC water oxidation and have fascinated much consideration. Herein, we spotlight mainly on heterogenous semiconductor-based photoanode materials for PEC water splitting. Different heterogeneous photocatalysts based materials are emphasized in different groups, such as oxynitrides, oxysulfides, and organic solids. Lastly, the design approach and future developments regarding heterogeneous photocatalysts oxide electrodes for PEC applications and photocatalytic applications are also discussed.

“…Stable organic semiconductor composed of p/n junction responsive to whole visible light was operated and utilized not only for photovoltaic (OPV), 1-10 but also photocatalyst. [11][12][13][14][15][16][17][18][19][20] For the design of efficient OSM photocatalyst, material selection for p-type and n-type is different from photovoltaic devices. In the case of photocatalyst, p-type is oxidation part and phthalocyanine (Pc) exhibited as a co-catalyst site.…”

The characteristics for 3,4,9,10-perylenetetracarboxylic-bisbenzimidazole (PTCBI, an n-type semiconductor) and 29H,31H-phthalocyanine (H 2 Pc, a p-type semiconductor) as organic p/n bilayer and bulk heterojunction (BHJ) photoelectrodes were studied for the photooxidation of thiol. Based on the analysis in their absorption spectra, a new absorption band in the longer wavelength (λ > 800 nm) for both bilayer and co-deposited photoelectrode suggested a formation of charge transfer complex. A photoanodic current was observed at λ~880 nm for the both bilayer and co-deposited electrodes, while no absorption and photocurrent for single layers of PTCBI and H 2 Pc. By assuming the Langmuir adsorption equilibrium at the solid/water interface, the kinetic parameters for the photoanodic current of thiol was analyzed for the longer wavelength of irradiation (λ~900 nm), and it was indicated that the rate of oxidation in the co-deposited was higher than that of the bilayer due efficient charge separation in the charge transfer complex.
