Precise fabrication of porous one-dimensional gC3N4 nanotubes doped with Pd and Cu atoms for efficient CO oxidation and CO2 reduction

Data on the catalytic CO oxidation and CO2 reduction durability on gC3N4 nanotubes Co-doped atomically with Pd and Cu

“…We tested the CO oxidation reaction in a fixed bed quartz tubular reactor connected to an online gas analyzer (IR200, Yokogawa, Japan) in the presence of 50 mg of each catalyst. Initial pretreatment was carried out at 250 °C under an O 2 flow of 50 mL min −1 for 1 h, and then H 2 (30 mL min −1 ) for 1 h. Following that, the catalysts were exposed to the gas mixture involving of 4% CO, 20% O 2 , and 76% Ar with a total flow of 50 mL min −1 under continuous heating from 25 °C to 400 °C (5°min −1 ) [1], [2], [3], [4], [5]. The percentage of CO conversion (% CO) was calculated using the following equation:…”

“…In particular, the addition of melamine and nitric acid should be sluggish to provide enough time for a consistent polymerization into uniform nanotubes. Nitric acid facilitates the deprotonation of active –NH 2 groups of melamine and allowing the conversion of melamine into melem and then to polymeric gC 3 N 4 composed of triazine-based units after carbonization at an elevated temperature [1], [2], [3], [4], [5]. Meanwhile, the concertation of Pd/Cu precursors should be lower to be anchored on the N-atoms of melamine and then facilitating the atomic doping of Pd/Cu instead of formation of nanoparticles [1], [2], [3], [4], [5].…”

The Recent Advances in the Mechanical Properties of Self-Standing Two-Dimensional MXene-Based Nanostructures: Deep Insights into the Supercapacitor

“…Thereby, the mechanical properties of self-standing MXens and their mechanism should be highlighted experimentally rather than through theoretically. Also, the combination between MXenes and other carbon-based materials and novel metallic nano architectonics can lead to impressive properties and applications [ 116 , 117 , 118 , 119 ]. Thus, the presented review can provide a guided roadmap for the scientists to design novel MXenes for the coming generations of energy conversion and storage devices as well as smart sensors.…”
