Hard Template Method

In this work, three-dimensional mesoporous MnO2, K/MnO2, Pt/MnO2 and K-Pt/MnO2 catalysts were prepared through hard-template method. The additional K/Pt had significantly improved the HCHO oxidation activity. The K-Pt/MnO2 catalyzed complete HCHO oxidation was achieved at 0℃ with space velocity (GHSV) at 50000 ml/(gand#183;h). With the excellent catalytic performance, K-Pt/MnO2 exhibited a higher ratio of Oads(surface adsorbed oxygen)/Olatt(surface lattice oxygen) and Mn3+/Mn4+ ions than the other catalysts. Meanwhile, it was still stable after running a 70h reaction. Overall, the K-Pt/MnO2 was a promising material for HCHO elimination.

Excellent Catalytic Performance

Fabrication of biomimetic materials and scaffolds is usually a micro- or even nanoscale process; however, most testing and all manufacturing require larger-scale synthesis of nanoscale features. Here, we propose the utilization of naturally prefabricated three-dimensional (3D) spongin scaffolds that preserve molecular detail across centimeter-scale samples. The fine-scale structure of this collagenous resource is stable at temperatures of up to 1200°C and can produce up to 4 × 10–cm–large 3D microfibrous and nanoporous turbostratic graphite. Our findings highlight the fact that this turbostratic graphite is exceptional at preserving the nanostructural features typical for triple-helix collagen. The resulting carbon sponge resembles the shape and unique microarchitecture of the original spongin scaffold. Copper electroplating of the obtained composite leads to a hybrid material with excellent catalytic performance with respect to the reduction of p-nitrophenol in both freshwater and marine environments.
