Article Abstract
With 28-34 times the greenhouse effect of CO over a 100-year period, methane is regarded as the second largest contributor to global warming. Reducing methane emissions is a necessary measure to limit global warming to below 1.5 °C. Photocatalytic conversion of methane is a promising approach to alleviate the atmospheric methane concentrations due to its low energy consumption and environmentally friendly characteristics. Meanwhile, this conversion process can produce valuable chemicals and liquid fuels such as CHOH, CHCHOH, CH, and CH, cutting down the dependence of chemical production on crude oil. However, the development of photocatalysts with a high methane conversion efficiency and product selectivity remains challenging. In this review, we overview recent advances in semiconductor-based photocatalysts for methane conversion and present catalyst design strategies, including morphology control, heteroatom doping, facet engineering, and cocatalysts modification. To gain a comprehensive understanding of photocatalytic methane conversion, the conversion pathways and mechanisms in these systems are analyzed in detail. Moreover, the role of electron scavengers in methane conversion performance is briefly discussed. Subsequently, we summarize the anthropogenic methane emission scenarios on earth and discuss the application potential of photocatalytic methane conversion. Finally, challenges and future directions for photocatalytic methane conversion are presented.

Emission factor data for existing heating appliances are being used to estimate achievable emission reductions with emerging heating technologies. However, the emission factors currently being used for modeling were developed prior to low-sulfur fuel standards and rely on a small number of studies, mostly focusing on steady-state operation. In this work, detailed emission measurements of typical heating equipment fired with natural gas and No.

The rapid growth of natural-gas vehicles (NGVs) necessitates robust catalysts for the simultaneous abatement of methane (CH), nitrogen oxides (NO), and carbon monoxide (CO) under fluctuating exhaust compositions. We reported a site-engineered MnGa@In-CHA OXZEO catalyst in which indium was confined within an SSZ-13 framework, and GaO and MnO phases were uniformly dispersed on its exterior. MnO markedly enhanced redox capacity, driving NO → NO oxidation and lowering the activation energy for C-H bond cleavage in CH, while GaO tuned the Brønsted acidity and mediated electron transfer among In, Mn, and Ga centers.

The electrochemical reduction of CO to CH offers a promising pathway for renewable energy storage, yet remains limited by sluggish kinetics, poor catalyst stability, and competing hydrogen evolution reactions (HER). Herein, a host-guest strategy is reported for engineering metal-organic frameworks (MOFs) through the encapsulation of conductive polymers to stabilize reticular skeletons and regulate interfacial water for efficient CO-to-CH conversion. Specifically, polypyrrole (PPy) and polyaniline (PANI) are confined within Cu-anchored UiO-67 frameworks, resulting in hybrid catalysts-PPy@Cu-UiO-67 and PANI@Cu-UiO-67-with preserved crystallinity and enhanced electronic conductivity.

Methane is a notorious and potent greenhouse gas with a greenhouse effect potential 25 times higher than carbon dioxide. Current technologies for methane are limited by high energy demands, CO emissions and by-product pollution, and costly catalysts. Hence, it is urgent to seek clean processing technologies that can utilize its dual properties as an energy source and raw chemical feedstock to unlock its full potential and contribute to environmental remediation.
