“…5c, SrTiO 3 only absorbs UV light, and its UV absorption sideband is approximately 400 nm. 43 The absorption of graphene in the visible-light region is stronger than that in the UV region. CSG-5 exhibits strong absorption in the UV region which extends to the visible-light range, consistent with the light absorption properties of CQDs.…”

“…Photothermal catalysis combines the high efficiency and durability of thermocatalytic oxidation with the low energy consumption of photocatalytic oxidation 14 . Plasma promotes the degradation of air pollutants, and photocatalysis reduces the formation of undesired by-products (e.g., NO x and O 3 ) that are often produced in plasma-driven catalysis 15 . Despite distinctive advantages, hybrid processes are still at an early stage, and more in-depth studies are required to elucidate the synergistic mechanisms and resolve practical engineering issues.…”

concentration for March 2021 was 417.14 parts per million (ppm), which is about 50% higher than the average for pre-industrial levels (i.e., 278 ppm). In order to control global warming, the CO 2 emission must fall by 25% to keep the temperature below 2 °C threshold relative to the pre-industrial climate. [3,4] Among the existing numerous renewable and sustainable energy resources such as wind, solar, hydropower, geo-thermal and ocean-energy, the consumption of unlimited solar energy become a vital alternative energy source, and has been extensively explored during the past few decades. [5] For instant, solar energy could be employed practically in photocatalysis for water splitting to generate hydrogen, carbon dioxide conversion to value added products, and pollutant oxidation. [6][7][8] Photocatalysis has advantage over conventional biological, incineration, electrocatalytic, adsorption, and air stripping treatment techniques because these methods always exhibit shortfalls such as instability, catalyst poisoning, low production yield, poor mechanical strength, time consuming, and electrode corrosion. [9,10] Generally, the photocatalytic process involves several essential steps such as the light absorption by photocatalyst to generate charge carriers, charge carrier's separation and migration to the photocatalyst surface, and the surface redox reactions to transform solar energy into chemical energy. [11,12] If these essential steps are satisfied by a proficient photocatalyst, then of course, high photocatalytic efficiency could be expected. Generally, the fundamental features of a photocatalyst include appropriate band gaps with their corresponding valence and conduction band potentials, surface active sites, surface area, and optical absorption behavior that govern the efficiency and effectiveness of photocatalytic processes. [13,14] Since the photocatalytic reactions are typically performed in water and air environments, therefore, the photocatalyst stability could be crucial under these circumstances. [15] Fujishima and Honda performed water splitting reaction for the first time in 1972, while utilizing TiO 2 photoanode with the aid of Pt as a counter electrode. [16] Afterward, TiO 2 photocatalyst received marvelous attention in photocatalysis owing to its promising features such as its non-toxic nature, water insolubility, nature abundant, hydrophilicity, high stability, and appropriate valence and conduction band potentials for redox reactions. [17] Yet, the Photocatalysis is an advanced technique that transforms solar energy into sustainable fuels and oxidizes pollutants via the aid of semiconductor photo catalysts. The main scientific and technological challenges for effective photocatalysis are the stability, robustness, and efficiency of semiconductor photocatalysts. For practical applications, researchers are trying to develop highly efficient and stable photocatalysts. Since the literature is highly scattered, it is urgent to write a critical review that summarizes the stateof theart progress in the ...
