“…Also, the maximum dispersion of metal particles without compromising the size-shape-dependent properties should be of concern. The recent reports on photocatalytic activity of GCN/ZnO modified with cocatalysts like NiCo alloy, Co-Pi particles, and metallic iron forefronts the use of affordable transition metal structures instead of costly noble metals. ,, The alloy particles induce the magnetic properties to the composite, helping in their speedy recovery, while Co-Pi shifts the Fermi level and results in upward band bending leading to efficient separation of charge carriers . The alloy modification ameliorates the advantages of bimetallic systems and unlocks a new avenue in the design of versatile ternary systems.…”

Heterostructuring the g-C 3 N 4 (GCN) with wide gap oxide photocatalysts is of prominent interest as they can harvest photons spanning the UV−visible region. In this regard, GCN/ZnO have garnered remarkable attention due to their admirable structure, optical, dimensional anisotropy, and electronic properties. The 2D sheet-like structure of GCN can serve as a suitable substrate for the growth of distinct ZnO nanostructures under the multitude of reaction conditions. This review focuses on the progress in the rational design and interface engineering of GCN/ZnO to from Type-II and Z/S-scheme heterojunctions, followed by their relevant photocatalytic applications toward H 2 evolution, CO 2 reduction, pollutant degradation, and bacteria inactivation. The mechanism underlying the crystallization of GCN and ZnO together with their intimate contact in the composite are emphasized under the light of diverse preparation methods. The modification of GCN/ZnO with cocatalysts such as metals, alloy, semiconductors, and carbon materials to form ternary systems to highlight their advancements. The gap analysis and future prospectus of this intricate heterostructure concerning the challenges in synthetic approaches and the charge carrier dynamics are discussed. This review envisages the development of efficient GCN/ZnO-based heterostructures for multiscale applications.

Conjunction of 1D as well as 2D carbonaceous materials (CMs) is of great importance because of the significant improvement in the optoelectronic properties. Through extensive optimization, a rapid, facile and heat-treatment free route is progressed which ensues 88.4 and 92.3% degradation of congo-red dye for CNTs/ZnO and g-C 3 N 4 /ZnO, respectively. g-C 3 N 4 /ZnO shows the highest value of correlation co-efficient (R 2 ) (0.9927) and rate constant (K C ) (0.0390 min −1 ) among all others. g-C 3 N 4 /ZnO-HPs 4 displays the highest potential of 1.54 V and over potential of 310 mV for current density value of 10 mA/ cm 2 compared to others composite while CNTs/ZnO-HPs 4 Tafel slope has a value of 42 mV/dec. Scanning and transmission electron microscopy, X-ray diffractometry and energy dispersive spectrometry were carried out to confirm the efficacy of nano-composites while electron LSV, Tafel slopes and Nyquist plots were plotted to reveal the consequent efficient electrocatalytic behavior. The modified recipe for the development of nanocomposites having CMs exhibited its potential for use in multiple engineering applications, including but not limited to photocatalysis and oxygen evolution reaction.
