A seaweed-like graphitic-C3N4 (g-C3N4 "seaweed") architecture has been prepared by direct calcination of the freeze-drying-assembled, hydrothermally treated dicyandiamide fiber network. The seaweed network mesoporous g-C3N4 nanofibers is favorable for light harvesting, charge separation and utilization active sites, highly efficient photocatalytic behavior water splitting. It exhibits a high hydrogen-evolution rate 9900 μmol h(-1) g(-1) (thirty times higher than that its bulk counterpart),...

Porous silicon carbide (SiC) has attracted considerable attention as an alternative catalyst support, particularly in corrosive and high-temperature environment. Herein, we report a facile strategy to controllably fabricate macroporous, meso-microporous macro-meso-microporous SiC ultrathin fibers (M-SFs, MM-SFs MMM-SFs, respectively) mats with good flexibility via electrospinning combined polymer-derived ceramics route. The formation mechanism of different porous structures been discussed....
Designing a novel heterojunction structure on SiC gas sensing material is extremely desirable for high-performance sensors applied in harsh environments. Inspired by the unprecedented catalyzing effect of single-atom catalysts, here, we have sequentially loaded tin oxide nanorods (SnO2 NRs) and platinum single atoms (Pt SAs) silicon carbide nanosheets (SiC NSs) to build Pt SAs@SnO2 NRs@SiC NSs multi-heterojunction. Gas based show highly enhanced performance, including high response (119.75 ±...
Rutile, anatase, and brookite TiO2 nanorods (TNs) with specific exposed crystal facets have been obtained by a hydrothermal method using peroxide titanic acid (PTA) solution of different pH values. Below pHPTA 10, the condensing complex is uncharged Ti2O5(OH)2(H2O)4 or cations Ti2O5(H2O)62+, corner-shared bonding easily occurs to form rutile phase. Above species anions Ti2O5(OH)4(H2O)22–, resulting in larger probability edge-shared which favor formation anatase TiO2. Brookite whose structure...

The HEEs are fabricated by photocatalytic deposition particles on nanotubes followed hydrophobization with vaporized octadecyltrimethoxysilane (OTS) molecules. surface subsequently regulated situ from hydrophobicity to hydrophilicity decomposition OTS molecules ultraviolet light....
Abstract One-dimensional electrospun nanofibers have emerged as a potential candidate for high-performance oxygen reduction reaction (ORR) catalysts. However, contact resistance among the neighbouring hinders electron transport. Here, we report preparation of interconnected Fe-N/C nanofiber networks (Fe-N/C NNs) with low electrical via electrospinning followed by maturing and pyrolysis. The NNs show excellent ORR activity onset half-wave 55 108 mV less than those Pt/C catalyst in 0.5 M H 2...
