Structured nanoporous copper catalysts prepared by laser powder bed fusion and dealloying for on-board methanol steam reforming

Refinement of nanoporous copper by dealloying the Al–Cu alloy in NaOH solution containing sodium dodecyl sulfate

“…It is in accordance with the previous finding. 47 The diffraction rings in the selected area electron diffraction (SAED) pattern (Fig. 2l) demonstrate that the dealloyed specimen is composed of polycrystalline Cu and Cu 2 O.…”

Hydrogen production from ethanol by steam reforming with recyclable NiCaOx/NaCl catalysts

“…Due to the insufficient conversion of ethanol at low temperature, a large amount of carbon will be deposited on the surface of the catalyst. 28 As the reaction proceeds to high temperature, the carbon deposition will further generate hydrogen with excess water. Therefore, the hydrogen yield of the catalyst will be close to 100%.…”

Electrochemical Synthesized Copper Mesh Catalysts for Methanol Steam Reforming

“…10,11 However, the conventional pellet catalysts for MSR are prone to physical breakage by frequent vibrations during vehicle movements, leading to catalyst deactivation and process shutdowns. 8,12 Three-dimensional structural catalysts based on metal foams or wire meshes have shown outstanding catalytic performance in the MSR reaction attributed to their favorable heat and mass transfer properties, high mechanical strength, and flexibility in flow channel layout design. 13−16 Liu et al observed that copper foam supports featuring surface microchannels enhance diffusion space and promote a more uniform methanol distribution, significantly improving MSR reaction performance.…”
