“…The precipitates are then calcined to obtain the desired metal oxide composition. Generally, oxalate precipitates show good stability towards different treatment conditions, such as washing and drying, and possess a relatively high production yield [454]. In addition, the high homogeneity of the electrolyte powders produced by this method commonly results in the report of high bulk conductivities [451].…”

Solid oxide fuel cells (SOFCs) are amongst the most widely used renewable alternative energy systems with near-zero carbon emission, high efficiency, and environment-friendly features. However, the high operating temperature of SOFCs is still considered a major challenge due to several issues regarding the materials’ corrosion, unwanted reactions between layers, etc. Thus, low-temperature SOFCs (LT-SOFCs) have gained significant interest during the past decades. Despite the numerous advantages of LT-SOFCs, material selection for each layer is of great importance as the common materials have not shown a desirable performance so far. In addition to the selection of the materials, fabrication techniques have a great influence on the properties of the SOFCs. As SOFCs with thinner layers showed lower polarisation resistance, especially in the electrolyte layer, different thin-film fabrication methods have been employed, and their effect on the overall performance of SOFCs has been evaluated. In this review, we aim to discuss the past and recent progress on the materials and thin-film fabrication techniques used in LT-SOFCs.

“…A clean energy system should generally utilize sustainable resources to supply reliable power at a low-levelized cost and high efficiency [4]. Clean energy systems such as fuel cells [5], batteries [6], solar cells [7], wind power [8], geothermal systems [9], biogas [10,11], thermoelectric materials [12], hydrogen energy [13], etc. can offer environmental, economic, and social advantages over the fossil fuels [14,15].…”

The thermochemical water-splitting method is a promising technology for efficiently converting renewable thermal energy sources into green hydrogen. This technique is primarily based on recirculating an active material, capable of experiencing multiple reduction-oxidation (redox) steps through an integrated cycle to convert water into separate streams of hydrogen and oxygen. The thermochemical cycles are divided into two main categories according to their operating temperatures, namely low-temperature cycles (<1100 °C) and high-temperature cycles (<1100 °C). The copper chlorine cycle offers relatively higher efficiency and lower costs for hydrogen production among the low-temperature processes. In contrast, the zinc oxide and ferrite cycles show great potential for developing large-scale high-temperature cycles. Although, several challenges, such as energy storage capacity, durability, cost-effectiveness, etc., should be addressed before scaling up these technologies into commercial plants for hydrogen production. This review critically examines various aspects of the most promising thermochemical water-splitting cycles, with a particular focus on their capabilities to produce green hydrogen with high performance, redox pairs stability, and the technology maturity and readiness for commercial use.

Electrosynthesis offers an efficient and sustainable strategy for the conversion of biomass‐derived platform molecules. Among this process, developing efficient and cost‐effective electrocatalysts is of vital importance. We report herein the preparation of the nanocrystalline PbO‐In2O3 catalysts for the electrocatalytic reduction of levulinic acid (LA) to valeric acid (VA). A series of non‐noble nanocrystalline PbO‐In2O3 composite materials with different molar compositions were prepared and thoroughly characterized. The prepared nanocrystalline PbO‐In2O3 composite materials were used as working electrode for the electrocatalytic hydrogenation of LA in an H‐type electrolytic cell. A LA conversion of 41.4 % and VA selectivity of 97.8 % was achieved with the VA faradic efficiency of 89.2 % under the high current density of 134 mA cm−2. This is the first report on the electrocatalytic reduction of LA to VA using PbO‐In2O3 composite electrode catalyst.
