“…[171,172] Especially, g-C 3 N 4 has been used in a variety of fields ranging from biosensing to catalysis; however, the majority of the publications are concentrated on CO 2 reduction, hydrogen evolution through water splitting, or organocatalysis due to its suitable band edge position and band gap. [173][174][175] Correspondingly, it has been utilized for pollutant degradation, [176] nitrogen fixation, [177] biodegradation, [178] etc. Yet, because of its weak electrical conductivity, it has not been explored to that level for electrocatalytic applications.…”

Inspired by natural photosynthesis, harnessing the wide range of natural solar energy and utilizing appropriate semiconductor‐based catalysts to convert carbon dioxide into beneficial energy species, for example, CO, CH4, HCOOH, and CH3COH have been shown to be a sustainable and more environmentally friendly approach. Graphitic carbon nitride (g‐C3N4) has been regarded as a highly effective photocatalyst for the CO2 reduction reaction, owing to its cost‐effectiveness, high thermal and chemical stability, visible light absorption capability, and low toxicity. However, weaker electrical conductivity, fast recombination rate, smaller visible light absorption window, and reduced surface area make this catalytic material unsuitable for commercial photocatalytic applications. Therefore, certain procedures, including elemental doping, structural modulation, functional group adjustment of g‐C3N4, the addition of metal complex motif, and others, may be used to improve its photocatalytic activity towards effective CO2 reduction. This review has investigated the scientific community's perspectives on synthetic pathways and material optimization approaches used to increase the selectivity and efficiency of the g‐C3N4‐based hybrid structures, as well as their benefits and drawbacks on photocatalytic CO2 reduction. Finally, the review concludes a comparative discussion and presents a promising picture of the future scope of the improvements.

Worldwide consumption, toxicity, and bioaccumulation of paracetamol (PCM) and atenolol (ATL) has drawn attention of researchers over last decades. A small portion of these drugs is absorbed by human body and rest of them is excreted through urine and feces to the environment (water bodies and soil) which might result in negative impacts. Nanocomposite of chromium oxide coupled with zinc hexacyanocobaltates (Cr 2 O 3 @ZnHCC) was synthesized by a green-method using Sapindus mukorossi seed-extract for the removal of targeted drugs. Microscopic and spectroscopic analysis of Cr 2 O 3 @ZnHCC showed uniformly incorporated prisms into cubic structure having ~75 nm particle size. Well-characterized Cr 2 O 3 @ZnHCC and individuals (Cr 2 O 3 & ZnHCC) were utilized for the degradation of PCM and ATL under direct sunlight and dark conditions. Highest degradation of targeted drugs (91%-94%) resulted at 20 mg L À1 concentration of pollutant, 25 mg of catalyst dose, and pH ~7 under daylight exposure (5 h). First-order kinetics followed with a high adsorption capacity, X m (13.4-14.5 mg g À1 ) value was obtained to confirm the strong binding with the pollutants. Moreover, Cr 2 O 3 @ZnHCC substantially suppressed the half-life of targeted drugs (PCM: 0.6 h; ATL: 2.9 h) and converted them into safer-small metabolites as confirmed by liquid chromatography-mass-spectrometry analysis, and the reduction of carbon content was confirmed by total organic carbon analysis. The charge separation mechanism was assisted by UV reflectance and photoluminescence data. The synthesized green-nano photocatalyst displayed high reproducibility (up to 10th cycle), sensitivity, and stability during the degradation process which makes this a suitable candidate for industrial applications.
