Sustainable strategy on microbial fuel cell to treat the wastewater for the production of green energy

A. Saravanan et al.

Summary: Microbial fuel cell (MFC) is a promising alternative energy system that converts chemical energy into electricity with the help of microorganisms. It consists of electrodes (anode and cathode), catalyst (microorganism), and proton transport/exchange membrane (PEM). MFC's core function is the oxidation of organic substrates and electron transfer, with key factors being microorganisms and electrodes. Besides electricity generation, MFC also finds applications in wastewater treatment, biofuel production, and biosensors.

Chemical strategies in molybdenum based chalcogenides nanostructures for photocatalysis

Syed Asim Ali et al.

Summary: In the past two decades, environmental issues caused by human activities for development have become more prominent. Ignoring climate change and the stagnant approach of major oil industries have resulted in the melting of glaciers and the shrinking of mountain peaks. The imbalance in natural resources is leading to various crises that can affect livelihoods. Photocatalysis, particularly using transition metal chalcogenides (TMCs), is considered a simple and sustainable technique to generate energy and degrade pollutants. Among TMCs, molybdenum chalcogenides nanostructures show exceptional properties and promise in efficient hydrogen production and dye degradation through photocatalytic water splitting. This review discusses the applications of Mo-based chalcogenides nanostructures in hydrogen production and dye degradation, as well as the progress made in enhancing their photocatalytic activity.

Type-II CuFe2O4/Graphitic Carbon Nitride Heterojunctions for High-Efficiency Photocatalytic and Electrocatalytic Hydrogen Generation

Amir Mehtab et al.

Summary: Solar water splitting for hydrogen energy storage has become increasingly important, and g-C3N4 is an ideal photocatalyst for this process due to its excellent alignment with water redox potentials. In this study, we developed a semiconductor heterostructure of g-C3N4 with CuFe2O4 nanoparticles, which greatly enhanced the photocatalytic efficiency. The CuFe2O4/g-C3N4 heterostructures exhibited up to a 2.5-fold improvement in catalytic efficiency, with an apparent quantum yield of hydrogen production reaching 25%. This improvement is attributed to the introduction of CuFe2O4 nanoparticles, which provide more active sites and reduce electron-hole recombination.

Summary: This study discusses the morphological changes of g-C3N4 after acidic exfoliation, analyzes the chemical purity of the synthesized materials, and investigates the electronic structure and elemental composition of g-C3N4. The dependency of the sacrificial agents of g-C3N4 is also discussed. The experimental results show that exfoliated g-C3N4 exhibits remarkable hydrogen evolution in the presence of TEOA.

Kumara Ramanatha Datta Kasibhatta et al.

Summary: This review critically examines the rapidly developing field of oxygen electrocatalysis, focusing on the design of efficient hetero atom doped graphene-based metal-free catalysts, defect engineering, and co-doping with special emphasis on electrochemical activity in acidic media. The latest trends in designing hetero atom doped graphene nanoarchitectonics for ORR and OER, along with important electrochemical parameters, are outlined. Additionally, it highlights the design of efficient and robust bi-functional hetero atom doped graphenes elucidating structure-property relationships toward multifunctional OER/ORR behavior.

Cation substitution of B-site in LaCoO3 for bifunctional oxygen electrocatalytic activities

Xingdong Jiang et al.

Summary: In this study, LaCoO3-based materials were modified by substituting the Co site with Mn, resulting in samples with different compositions. The introduction of Mn led to an increase in the content of active Mn4+ and Co3+, improving the electrocatalytic activities. The optimization of oxygen catalytic activities was attributed to the increased electrical conductivity and the presence of Mn4+ and Co3+ ions.

Summary: Perovskite oxides, specifically Ce-doped LaCoO3, synthesized using microwave/ultrasound-assisted hydrothermal methods, exhibit efficient catalytic performance in oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The excellent electrocatalytic activity and long-term durability in alkaline conditions are attributed to the synergistic effects of excellent conductivity and enriched active sites resulting from A-site substitution.
