Current Scenario

Background: Rapid escalation in textile, paper, pesticides, pharmaceuticals and several other chemical based manufacturing industries due to amplification in human requirements have proportionately contributed to the extreme contamination of water ecosystem, resulted from the discharge of toxic pollutants from industries. Effluents from textile industries are comprised of coloured dyes like Rhodamine B, Methyl Orange, Methylene Blue and phenolic compounds which deserve special mention owing to their non-biodegradable, carcinogenic and severe detrimental nature. Urgent needs to ameliorate this fast declining environmental situation are of immense necessity in current scenario. Objectives: Objectives: In this regard, graphitic carbon nitride (GCN) is a distinguished material for water purification-based applications because of its exclusive characteristics making it highly prospective for degradation of toxic dyes from water by catalysis and adsorption techniques. GCN has been a material of conspicuous interest in recent times owing to its two dimensional sheets like structure with favourable surface area, and cost-effective synthesis approaches along with high production yield. This article presents a detail study of different aspects of GCN as a material of potential for water purification. Through extensive literature survey it has been shown that GCN is an effective material to be used in the fields of application. Several effective procedures like catalysis or adsorption for removal of dyes from water have been discussed with their basic science behind. Conclusions: This systematic effort shows that GCN can be considered to be one of the most efficient water purifier with further advantages arising from its easy and cost effective large scale synthesis.

Background: The Present Scenario Of Rapid Industrial And Population Growth Has Become A Serious Threat To Environmental And Energy Concerns. Extremely Noxious Pollutants Like Dyes, Heavy Metal Ions, Phenols, Antibiotics And Pesticides In Water Are The Reason Behind Deprived Water Quality Leading To Inadequate Access To Clean Water. Photocatalysis Is A Prominent Strategy For Environmental Remediation As Photocatalytic Materials Not Only Convert Solar Energy Into Usable Energy Expedient But Also Shows Potential Application In Pollutant Mitigation. An Effectual Photocatalytic System Must Possess Wide Visible Absorption Range, High Physio-Chemical Firmness, And Effective Space-Charge Separation Along With Strong Redox Ability. Polymeric Graphitic Carbon Nitride A Metal-Free Semiconductor Photocatalyst Has Outshined As A Robust Photocatalyst For Various Photocatalytic Applications. Method: Hybridizing Polymeric G-C3n4 With Other Semiconductor Photocatalysts Has Not Only Conquer The Limitations Related To Pristine G-C3n4 But Also Displayed Improved Photoactivity. Different Photocatalytic Systems Involving G-C3n4 Coupled Metal-Oxides, Metal-Free Systems And Complex Heterojunction Systems Are Reviewed. Moreover, An All-Embracing Study Based On G-C3n4 Based Nanocatalysts Is Explored Via Heterojunction Formation Taking G-C3n4 As One Component. Results: Photocatalytic Experiments Involving Photodegradation Of Pollutants, Revealed The Significance Of Metal-Free G-C3n4 In The Heterojunction System Which Remarkably Boost The Photoactivity Through Effective Separation And Migration Of Photocarriers. Moreover, From Recyclability Experiments, Exceptional Photostability Of G-C3n4 Based Photocatalysts Was Observed. Photocatalytic Pollutant Degradation Is A Complex Phenomenon Which Requires Significant Experimental Techniques To Support The Mechanism. With The Help Of Photoelectrochemical Analysis, The Mechanisms Behind Photodegradation Can Be Evaluated And Explored. Conclusion: Metal-Free Polymeric G-C3n4 Is A Potential Semiconductor Photocatalyst Which Can Be Optimally Utilized For Wastewater Treatment. Coupling G-C3n4 With Another Semiconductor Material With An Appropriate Band Edge Can Effectively Enhance The Photocatalytic Efficacy. Herein, G-C3n4 Derived Metal-Oxide, Metal-Free And Complex Heterojunction Systems Are Explored And Their Photocatalytic Efficiency Is Evaluated For Pollutant Degradation. However, More Effective Research Efforts Are Needed For Large-Scale Applications Of G-C3n4 Based Photocatalysts.
