Compared with pristine CSS-QDs, Ni and Pt cocatalysts boosted the catalytic activity by ∼4.5-fold and ∼51.2-fold, respectively, with Pt delivering a breakthrough activity enhancement. Systematic experiments revealed that Ni remained predominantly in ionic form during the reaction, while Pt existed in the form of elemental and oxide nanoparticles anchored on the CSS-QDs surface. The stronger interfacial interaction and faster electron transfer between Pt and CSS-QDs accounted for the superior catalytic performance.

Emphasis is placed on the relationships between catalyst structure, surface acidity/basicity, and catalytic performance. Incorporation of alkali (K<sup>+</sup>, Na<sup>+</sup>, Li<sup>+</sup>) and alkaline earth (Ca<sup>2+</sup>, Mg<sup>2+</sup>) metal ions into ceramic frameworks enhances active-site density, reactant adsorption, and reaction kinetics, enabling biodiesel yields exceeding 90%–99% under optimized conditions. The effects of framework topology, pore architecture, and surface area on mass transfer and catalyst accessibility are discussed, together with the roles of zeolites, clays, and mesoporous aluminosilicates in improving catalyst stability, reusability, and resistance to leaching. Current challenges, including catalyst deactivation, feedstock impurities, and scale-up limitations, are critically evaluated.

Conventional membranes face a “permeability–selectivity trade-off,” especially under high salinity and competitive conditions. This review examines advances in lithium-selective membranes, from basic size-sieving and charge regulation to biomimetic channels using molecular recognition and asymmetric gating. Beyond these conventional approaches, we emphasize a pivotal and necessary paradigm shift in ion transport strategy to address the limitations of traditional “forward-flow” separation. Specifically, we highlight our recent research into the design of artificial cation–chloride cotransporters, which bypasses the constraints of salt-induced Debye screening by facilitating electroneutral ion pair migration, thereby enabling resilient lithium extraction from concentrated brines. Furthermore, we discuss the “reverse lithium extraction” paradigm, a strategic reassessment of separation strategy that prioritizes the selective retention of Li<sup>+</sup> within the membrane matrix. By allowing competing cations to permeate freely while trapping the target species, this “reverse sieving” strategy effectively sidesteps the overwhelming competitive pressure characteristic of seawater mining.
