Abstract
The conversion of CO2 to hydrocarbons via the methanol-mediated pathway represents a crucial route for carbon neutrality, yet preferable production of more value-added light olefins remains constrained by the fundamental activity-selectivity trade-off in zeolite catalysts. While previous studies established an acidity regulation mechanism based on balancing acid density with acid strength, the conversion of methanol intermediates is also critically governed by their intracrystalline diffusion, which can be severely hindered by structural defects particularly prevalent in highly siliceous zeolites. This work demonstrates a different approach that synergistically integrates zeolite acidity and defect…
