Plasma-induced methane pyrolysis is a promising hydrogen production method. However, few studies have focused the decomposition of pure methane as a discharge gas. Herein, a rotating gliding arc reactor was used for the conversion of methane (discharge gas and feedstock) into hydrogen and solid carbon.

- Passive radiative cooling is a sustainable method for cooling the Earth that doesn't rely on energy consumption, focusing on the study of five metal-organic frameworks (MOFs) to improve this technology.
- The research reveals that the cooling effectiveness of these MOFs is mainly determined by their optical properties, although other characteristics like chemical composition are also important.
- UiO-66(Zr) stands out as the most effective MOF, with high solar reflectance and mid-infrared emissivity, showing significant cooling capabilities, including lowering temperatures by up to 5 °C.
Pseudocapacitive materials encapsulated in conductive carbon matrix are of paramount importance to develop energy storage devices with high performance and long lifespan. Here, via simple laser-scribing, the Mn-based metal-organic framework [EG-MOF-74(Mn)] is transformed into pseudocapacitive hybrid MnO/Mn C encapsulated in highly conductive graphitic carbon. It is revealed that the rapid carbothermic reduction of MnO (C + MnO → C' + Mn C + CO) leads to the formation of the intermediate pseudocapacitive MnO/Mn C and the concurrent catalytic graphitization of disordered carbon.
