Progress on photothermal catalytic methane low-carbon conversion technology
摘要
Abstract
Driven by the goal of"carbon neutrality",the efficient conversion and low-carbon utilization of methane have become a research focus in the field of energy chemistry.Traditional thermal catalytic techniques face bottlenecks due to their reliance on fossil fuels and high carbon emissions.Meanwhile,solar-driven photothermal catalytic technology offers a novel pathway for methane conversion through the synergistic mechanisms of photon excitation and thermal activation.The progress on three typical photothermal catalytic methane conversion technologies:Steam methane reforming,methane dry reforming and methane cracking was systematically reviewed.The breakthroughs in energy transfer optimization,catalyst design and system integration were mainly discussed.The photothermal coupling effect significantly reduced the methane activation barrier through the reconstruction of localized photothermal fields and electronic state regulation.The interface charge separation and oxygen vacancy engineering of nano-structured catalysts improved their anti-coking performances and reaction selectivities.Reactor designs combined with energy storage technologies optimized the dynamic utilization efficiency of solar energy.Although significant progress has been made on photothermal catalytic mechanism and energy-mass transfer,it is necessary to improve the stability of broadband light-absorbing materials and heat and mass transfer efficiency of large-scale reactors,and optimize multi-field coupling of light-heat-matter.In the future,it is necessary to focus on the development of multi-energy synergistic systems and intelligent control strategies to promote the advancement of photothermal catalytic methane conversion technologies towards low-carbon and high-value industrial application systems.关键词
