SWOT analysis of photocatalytic materials towards large scale environmental remediation

Oil and Gas Produced Water Reuse: Opportunities, Treatment Needs, and Challenges

“…For beneficial reuse, treatment trains might require a process dedicated to reducing the toxicity of the treated produced water to ensure public and environmental safety. Recently, promising studies have shown that photocatalysis-driven advanced oxidation processes (ozonation, rare metal catalyst, Fenton processes) can greatly reduce produced water toxicity. − Other technologies and processes have shown a potential for reducing toxicity, such as adsorption (granulated activated carbon, powder activated carbon, zeolite), , ion exchange, and biological treatments (activated sludge, MBR) − but require more research to determine their applicability for produced water treatment . Furthermore, if primary, secondary, and tertiary treatments are needed to meet effluent requirements, ensure sustainability, and address public concerns, the resulting treatment system may not be economically viable.…”

Visible light responsive heterostructure HTDMA-BiPO4 modified clays for effective diclofenac sodium oxidation: Role of interface interactions and basal spacing

“…Based on the reported research, photocatalytic technology has shown low mass transfer (primarily when naked semiconductors are used), generation of by-products, surface deactivation, and complicated or/and expensive synthesis of materials, and so on, as discussed recently by Djellabi et al [13]. For better technology transfer, several approaches have been suggested to overcome such drawbacks.…”

Solar Light Photoactive Floating Polyaniline/TiO2 Composites for Water Remediation

“…Therefore, water reuse has emerged as an important challenge, especially in regions suffering from water scarcity. Moreover, in addition to traditional pollutants, the presence of new contaminants in polluted water has become a global issue because conventional wastewater treatment processes lead to an incomplete removal of these recalcitrant compounds [1][2][3][4]. As a consequence, the scientific community has addressed its efforts to the development of highly efficient low-cost and low-impact treatments.…”

“…Advanced oxidation processes (AOP) offer important alternative perspectives to sorption processes [2,26]. Among these approaches, photocatalytic degradation has a special place, being able to degrade many pollutants without the addition of chemical oxidants under mild operating conditions [2,[27][28][29][30].…”

“…Advanced oxidation processes (AOP) offer important alternative perspectives to sorption processes [2,26]. Among these approaches, photocatalytic degradation has a special place, being able to degrade many pollutants without the addition of chemical oxidants under mild operating conditions [2,[27][28][29][30]. In recent years, the attention of the scientific community towards photodegradation processes under sunlight has gradually grown [31][32][33], as have investigations of recyclability and regeneration tests on photoactive materials [34][35][36].…”
