A viable alternative to non-renewable hydrocarbon fuels is hydrogen gas, created using a safe, environmentally friendly process like water splitting. An important role in water-splitting applications played by the development of two-dimensional (2D) layered transition metal chalcogenides (TMDCs), carbides (MXenes), graphene-derived 2D nanomaterials, phosphorene, and hexagonal boron nitride. Advanced synthesis methods characterization instruments enabled an effective application for improved electrocatalytic splitting sustainable production. Enhancing active sites, modifying phase electronic structure, adding conductive elements metals, forming heterostructures, altering defect state, etc., can improve catalytic activity stacked hybrid monolayer nanomaterials. The majority global research focused on finding safer substitutes petrochemical fuels, this review summarizes recent advancements field nanomaterials industrial-scale green production fuel cell applications.

The inherent porosity of covalent organic frameworks (COFs) establishes 1D conduits capable facilitating swift proton transport while effectively impeding the passage other species. This characteristic positions them as a promising avenue for engineering advanced exchange membranes in future. However, precise manner which structural attributes COF materials facilitate transportation process remains enigmatic. study delves into intricacies mechanism within COFs, using β-ketoenamine-based COFs TpPa and TpPa-SO3H exemplars. By employing ab initio molecular dynamics reactive force field simulations, we elucidate process. Our findings unveil that confined pore channels, protons showcase remarkable conductivity, primarily due to establishment hydrogen bond network involving adsorbed water molecules surface structure. interaction leads conductivity levels impressive 10–1 S/cm. Various factors, including humidity levels, functional group decoration, stacking arrangements, exert varying degrees influence on conduction Moreover, at interface between water, presence sulfonic acid groups significantly reduces free energy barrier ingress thereby contributing heightened observed experimental settings. These unveiled mechanisms influencing factors hold promise guiding selection design with exceptional performance.
