“…As a result, establishing a clean and sustainable energy supply system has become a worldwide concern. − Hydrogen has been recognized to be one of the most ideal energy carriers because of its unique advantages, for example, high burning heat value, zero pollution, and ease of use. Production of hydrogen by electrocatalytic decomposition of water is a method with great application potential. − It includes the hydrogen evolution reaction (HER) at the cathode and the oxygen evolution reaction (OER) at the anode. , Efficient electrocatalysts play an important role in accelerating water decomposition in practical applications. Although Pt-and Ru/Ir-based precious metal materials have been applied as efficient electrocatalysts in HER and OER, respectively, their low reserves and high prices limit their large-scale applications .…”

Recently, developing economical electrocatalysts with high performance in water decomposition has become a research hotspot. Herein, two kinds of cobalt-hybridized Cu 3 P nanostructure array electrocatalysts (including highly mesoporous 2D nanosheets and sugar gourd-like 1D nanowires) were controllably grown on a nickel foam substrate through a simple hydrothermal method combined with a subsequent phosphating treatment method. An electrocatalytic test indicated that the as-prepared 2D nanosheet array exhibited excellent activity and stability toward hydrogen evolution reaction under alkaline conditions, which offered a low overpotential of 99 mV at 10 mA/cm 2 and a small Tafel slope of 70.4 mV/dec, whereas a competitive overpotential of 272 mV was required for oxygen evolution reaction. In addition, the 2D nanosheet array delivered a low cell voltage of 1.66 V at 10 mA/cm 2 in a symmetric two-electrode system, implying its huge potential in overall water decomposition. The electrocatalytic performance is superior to the as-prepared 1D nanowire array and most of the Cu 3 P-related electrocatalysts previously reported. Experimental measurements and first-principles calculations show that the excellent performance of the 2D nanosheet array can be attributed to its unique 2D mesoporous structure and hybridization of cobalt, which not only provide a large electrochemically active surface and fast electrocatalytic reaction kinetics but also weaken the binding strength of electrocatalytic reaction intermediates. The present study provides a simple and controllable approach to synthesize Cu 3 P-based bimetallic phosphide nanostructures, which can be used as boosting Janus electrocatalysts for water decomposition.

“…As an important type of electrode material for SIBs, anode materials have been widely studied ( Tao et al, 2021 ). Until now, considerable achievements have been made in the research of SIB anode materials, such as layered transition metal oxides ( Xiong et al, 2011 ; Ma et al, 2020 ; Li Y. et al, 2020 ), polyanionic compounds ( Li et al, 2015 ; Yu et al, 2018 ; Guo et al, 2020 ; Sui Y. et al, 2021 ), metal sulfide composites ( Cui et al, 2018 ; Zhao et al, 2020 ), or alloy composites ( Liu et al, 2016 ; Tao et al, 2021 ) . Metal sulfide anodes have a higher sodium storage capacity, and generally have lower redox potential, better electrochemical reversibility, and longer cycle life than metal oxides in charge/discharge reaction ( Xie et al, 2018 ; Liu G. et al, 2019 ; Xu et al, 2019 ; Yao et al, 2019 ; Shan et al, 2020 ).…”

Recently, sodium-ion batteries (SIBs) have attracted extensive attention as potential alternatives to lithium-ion batteries (LIBs) due to the abundance, even distribution, low cost, and environmentally friendly nature of sodium. However, sodium ions are larger than lithium ions so that the anode materials of LIBs are not suitable for SIBs. Therefore, many negative electrode materials have been investigated. Among them, Sb2S3-based nanomaterials have gradually become a research focus due to their high theoretical specific capacity, good thermal stability, simple preparation, and low price. In this review, the research progress of Sb2S3-based nanomaterials in the SIB field in recent years is summarized, including Sb2S3, Sb2S3/carbon composites, Sb2S3/graphene composites, and Sb2S3/MxSy composites. Furthermore, the challenges and prospects for the development of Sb2S3-based nanomaterials are also put forward. We hope this review will contribute to the design and manufacture of high-performance SIBs and promote its practical application.

“…Biomass is an abundant and renewable source, thus introducing the promising potential for replacing fossil sources. Therefore, its use would contribute to the carbon neutrality of the energy sector, arising as an increasingly plausible alternative to fossil fuels [6][7][8][9]. However, there is a debate regarding sustainability and carbon-neutrality characteristics when converting 1st-generation biomass, i.e., edible biomass compromising with the food and animal feed.…”

Biomass is often referred to as a carbon–neutral energy source, and it has a role in reducing fossil fuel depletion. In addition, biomass can be converted efficiently into various forms of biofuels. The biomass conversion processes involve several thermochemical, biochemical, and hydrothermal methods for biomass treatment integration. The most common conversion routes to produce biofuels include pyrolysis and gasification processes. On the other hand, supercritical water gasification (SCWG) and hydrothermal liquefaction (HTL) are best suitable for converting biomass and waste with high moisture content. Despite promising efficiencies, SCWG and HTL processes introduce operational issues as obstacles to the industrialization of these technologies. The issues include process safety aspects due to operation conditions, plugging due to solid deposition, corrosion, pumpability of feedstock, catalyst sintering and deactivation, and high production costs. The methods to address these issues include various reactor configurations to avoid plugging and optimizing process conditions to minimize other issues. However, there are only a few studies investigating the operational issues as the main scope, and reviews are seldomly available in this regard. Therefore, further research is required to address operational problems. This study reviews the main operational problems in SCWG and HTL. The objective of this study is to enhance the industrialization of these processes by investigating the operational issues and the potential solutions, i.e., contributing to the elimination of the obstacles. A comprehensive study on the operational issues provides a holistic overview of the biomass conversion technologies and biorefinery concepts to promote the industrialization of SCWG and HTL.
