“…In various chemical processes of coal, coking is the earliest and still the most important method. 21 Coal coking is also known as coal destructive distillation at a high temperature, in which coal is used as raw material, heated to about 950 °C under the condition of air isolation. In this process, coke, coal tar, and coal gas can be produced; meanwhile, other chemical products can be recovered.…”

Coal resources are one of the key energy sources and essential for modern economic development. Despite the traditional coal industries having made considerable contributions to chemical production and energy storage, the accompanying environmental pollution and high energy consumption have also arisen that cause significant influence of the ecological balance. Hence, there is an urgent need to exploit feasible approaches to the sustainable utilization of coal resources. This review begins with a comprehensive summary of the representative coal chemistry technologies with critical discussions. Subsequently, a novel strategy coupled with green hydrogen is discussed for sustainable conversion of coal and highly efficient manufacture of downstream products. Moreover, the unique role of coal in terms of high-value-added carbon material production is highlighted as a low-cost resource for distinct applications. Finally, we propose several future directions for advanced coal chemistry development.

“…Acetylene (C 2 H 2 ) is an essential gas in industrial applications and a key component of industrial and consumer products/chemicals. , It can also be generated in oil-insulated and paper power transformers due to local overheating and discharge . Ideally, acetylene is an unsaturated, toxic, unstable hydrocarbon that can explode violently upon heating/mixing with air, reaching a flame temperature of up to 3300 °C .…”

Structural materials with shorter gas diffusion pathways, lower electrical resistance, and crystal size play a vital role in resistive-type gas sensors. In the present work, ZnO was doped with Ga to lower its electrical resistance and inhibit crystal growth for acetylene sensing. Ga-doped ZnO microbelts were synthesized by electrospinning a solution containing metal precursors and quillaja saponin as a template for the evolution of the belt structure, followed by calcination to achieve microbelts with a BET surface area of 68.5 m2 g–1, an average pore size of 4.6 nm, and ZnO crystals as small as 16.5 nm. The Ga-doped ZnO microbelts exhibited a response (R a/R g) of up to 21.0, and a fast response (7.6 s) to 20 ppm acetylene at 400 °C in dry conditions. The materials also showed outstanding repeatability of response of 10.04 ± 0.04 against 10 cycles of 5-ppm acetylene, a response of 2.0 to acetylene as low as 0.2 ppm, and excellent selectivity against 5 ppm of hydrogen, pentane, toluene, carbon monoxide, and methane. The results suggested that Ga doping could effectively improve the electrical conductivity and acetylene sensing performance of ZnO-based sensors.
