The zero-carbon emission with high purity marks its footprint towards industrialization. However, achieving commercial-scale current density with utmost durability has been a challenge for the research community. Several technical obstacles need to be overcome before its full promise can be realized as a potential alternative to fossil fuels. This review explores the advantages and limitations of non-noble electrocatalysts, highlighting promising strategies such as 3D substrate integration and binder-free synthesis, which enhance water electrolysis and electrochemical performance for industrial hydrogen generation. Promising approaches to effective water dissociation using 3D substrate material are outlined in the work, along with the advantages of binder-free synthesis and sophisticated manufacturing processes that could simplify electrode design while lowering costs and improving performance. This review offers an essential viewpoint on the engineering of green hydrogen in the future by combining these methods.

In order to study the changing characteristics of coal's functional groups and coal's chemical structure on porosity and permeability and its microscopic change mechanism, industrial analysis, elemental analysis, X-ray photoelectron spectroscopy (XPS), Raman spectroscopy (Raman) and carbon-13 nuclear magnetic resonance spectroscopy (<small><sup>13</sup></small>C-NMR) were used to analyze the functional groups and chemical structure of coal, and CT scanning and numerical simulation software were used to study the changes in pore cracks before and after freezing the coal body and to conduct quantitative analysis. Results show that with an increase in coal metamorphism, the chemical structure parameters of coal, such as the content of aromatic carbon, order degree, and bridge carbon ratio, increase. The change rate of the porosity and permeability of low-rank coal is higher than that of high-rank coal. The higher the aromatic carbon content of the coal sample, the smaller the porosity change rate and permeability change rate after liquid nitrogen freezing. The higher the oxidation degree (oxygen-grafted carbon, oxygen-grafted aromatic carbon, and carbonyl–carboxyl carbon) of the coal sample, the larger the rate of change in the porosity and permeability after liquid nitrogen freezing.
