B-doped 3C-SiC nanowires have been synthesized via a facile and simple carbothermal reduction method at 1500 °C for 2 h in a flowing purified argon atmosphere. The obtained nanowires possess a single crystalline and finned microstructure with fins about 100–200 nm in diameter and 10–20 nm in thickness. The diameter of the inner core stem is about 80 nm on average. Due to the smaller band gap, the finned microstructure and the single crystalline nature, the B-doped 3C-SiC nanowires demonstrate efficient activity as high as 108.4 μmol h−1 g−1 for H2 production, which is about 20 times higher than that of 3C-SiC nanowhiskers and 2.6 times higher than the highest value reported in the literature for SiC materials.

Nanoscale is a high-impact international journal, publishing high-quality research across nanoscience and nanotechnology. Nanoscale publishes a full mix of research articles on experimental and theoretical work, including reviews, communications, and full papers. Highly interdisciplinary, Nanoscale appeals to scientists, researchers and professionals interested in nanoscience and nanotechnology, quantum materials and quantum technology, including the areas of physics, chemistry, biology, medicine, materials, energy/environment, information technology, detection science, healthcare and drug discovery, and electronics. For publication in Nanoscale, papers must report high-quality reproducible new work that will be of significant general interest to the journal's wide international readership. Nanoscale is a collaborative venture between the Royal Society of Chemistry Publishing and a leading nanoscience research centre, the National Center for Nanoscience and Technology (NCNST) in Beijing, China. image block The journal publishes weekly issues, complementing and building on the nano content already published across the Royal Society of Chemistry Publishing journal portfolio. Since its launch in late 2009, Nanoscale has established itself as a platform for high-quality, cross-community research that bridges the various disciplines involved with nanoscience and nanotechnology, publishing important research from leading international research groups.
