“…The inclusion of the fuel cell increased the rate constant from 0.318 h −1 photocatalytically, i.e., without the fuel cell, to 0.555 h −1 . The configuration of Nordin et al [104] examined the use of three different photocatalysts (TiO2, ZnO, α-Fe2O3) immobilised on carbon cloth for the fuel cell photoelectrode, of which ZnO generated the highest opencircuit potential of 82.3 mV and a photocurrent of ~0.085 mA. The second cell used a carbon plate anode and an iron plate cathode, forming a peroxi-coagulation cell.…”

The photoexcitation of suitable semiconducting materials in aqueous environments can lead to the production of reactive oxygen species (ROS). ROS can inactivate microorganisms and degrade a range of chemical compounds. In the case of heterogeneous photocatalysis, semiconducting materials may suffer from fast recombination of electron–hole pairs and require post-treatment to separate the photocatalyst when a suspension system is used. To reduce recombination and improve the rate of degradation, an externally applied electrical bias can be used where the semiconducting material is immobilised onto an electrically conducive support and connected to a counter electrode. These electrochemically assisted photocatalytic systems have been termed “photoelectrocatalytic” (PEC). This review will explain the fundamental mechanism of PECs, photoelectrodes, the different types of PEC reactors reported in the literature, the (photo)electrodes used, the contaminants degraded, the key findings and prospects in the research area.

“…Hence, for complete exploitation of electro-Fenton potential, it could be integrated with other wastewater treatment systems to design a hybridized process. Previous researchers have designed various incorporated methods including electro-Fenton integrated with membrane filtration system (Yang et al, 2019 ), integration of electro-Fenton with AOPs (Oriol et al, 2019 ), electro-Fenton as pretreatment to biological methods (Changotra et al, 2019 ; Popat et al, 2019 ), and electro-Fenton-driven systems integrated with electrochemical methods like electro-oxidation and electrocoagulation (Nordin et al, 2019 ; Zazou et al, 2019 ). According to the findings of past investigations, combined methods due to the feasibility of offering lower operating costs present outstanding overall efficiency, especially in terms of energy consumption in comparison with individual electro-Fenton treatment units.…”

“…Pt-decorated Si PVC, Pt modified Buried Junction Silicon (BJS), have also been utilized as cathode, where a Si PVC has been incorporated with Pt cathode for efficient charge generation and transfer ( Chen et al, 2014 ; Xia L. et al, 2016 ; Zhao et al, 2017 ; Zeng et al, 2018b ). The search for a low-cost alternative for Pt led the researchers towards copper based, carbon-based and graphene-based materials which provide similar electrical conductivity and stability as Pt ( Canterino et al, 2009 ; Sfaelou et al, 2012 ; Ye et al, 2018 ; Liu X. H. et al, 2019 ; Nordin et al, 2019 ). A recent report analyzed the activity of various cathode materials for PFC.…”

The rising demand of energy and lack of clean water are two major concerns of modern world. Renewable energy sources are the only way out in order to provide energy in a sustainable manner for the ever-increasing demands of the society. A renewable energy source which can also provide clean water will be of immense interest and that is where Photocatalytic Fuel Cells (PFCs) exactly fit in. PFCs hold the ability to produce electric power with simultaneous photocatalytic degradation of pollutants on exposure to light. Different strategies, including conventional Photoelectrochemical cell design, have been technically upgraded to exploit the advantage of PFCs and to widen their applicability. Parallel to the research on design, researchers have put an immense effort into developing materials/composites for electrodes and their unique properties. The efficient strategies and potential materials have opened up a new horizon of applications for PFCs. Recent research reports reveal this persistently broadening arena which includes hydrogen and hydrogen peroxide generation, carbon dioxide and heavy metal reduction and even sensor applications. The review reported here consolidates all the aspects of various design strategies, materials and applications of PFCs. The review provides an overall understanding of PFC systems, which possess the potential to be a marvellous renewable source of energy with a handful of simultaneous applications. The review is a read to the scientific community and early researchers interested in working on PFC systems.
