Summary: A novel rGO@a-MnO2 catalyst, prepared by doping 3D snowflake graphene into a-MnO2, is able to enhance the catalytic activity at low temperature. The catalysts exhibit larger specific surface area and pore volume compared to a-MnO2, facilitating sufficient contact reaction between active component and VOCs. The presence of a unique graphene electronic bridge promotes electron transfer, leading to increased surface defects and more surface adsorbed oxygen. The catalyst doped with 4% 3D snowflake graphene shows the best activity, achieving 90% toluene conversion at 155°C and even 100% toluene conversion with 80% CO2 selectivity at 200°C.

Summary: The gas sensing properties of Pt/α-Ga2O3:Sn/Pt metal-semiconductor-metal (MSM) structures based on epitaxial films of α-Ga2O3 with Pt contacts were investigated. The structures showed high sensitivity to H-2, and it was found that the Pt contacts and Sn doping level played a key role in determining the hydrogen sensing properties. The sensitivity to H-2 was attributed to the modulation of the Schottky barrier height between Pt and α-Ga2O3:Sn.

Summary: In order to ensure worker and environmental safety, it is necessary to develop wearable sensing devices for detecting volatile organic compounds (VOCs) leakage in chemical production. This study focuses on methanol gas and constructs a wearable gas sensor on a flexible substrate to investigate its sensing process, performance, and practicality. The constructed sensor demonstrates electrocatalytic capability, good linearity, low limit of detection, high reproducibility and sensitivity, and selective detection of methanol in the presence of other interference gases. It also shows detectability in actual methanol gasoline samples with quick response time. Experimental results suggest that a higher content of platinum improves CO-tolerance capacity and sensing sensitivity, and the use of support materials with high specific surface area and conductivity can further enhance sensing sensitivity and be extended to the design of other VOCs sensors.

Summary: This study reports the unique flexibility of metal-organic framework Zn(int)(Ad) (TIF-A1) induced by acetylene adsorption, characterized by single-crystal X-ray diffraction and molecular modeling. The findings reveal that the flexibility of TIF-A1 originates from the strong interaction between acetylene and the framework, which results in the rotation of the int ligand and expansion of the framework simultaneously. This work provides insights into the flexibility of MOFs and guides the exploration of new flexible MOFs in the future.

Summary: A method of integrating the soft porosity and electrical properties of metal-organic frameworks (MOFs) into a single material is achieved through the design of conductive-on-insulating MOF (cMOF-on-iMOF) heterostructures. The cMOF-on-iMOF heterostructures exhibit enhanced selective sorption of CO2 and flexibility in sensing and electrical shape memory. These properties are attributed to the porous interface formed by the hybridization of both frameworks at the molecular level, as observed through operando synchrotron grazing incidence wide-angle X-ray scattering measurements.
