“…Comparative studies demonstrated that this heterojunction structure substantially promoted photocatalytic hydrogen evolution compared to pure In 2 S 3 and In 2 O 3 . However, research on enhancing the photocatalytic hydrogen evolution performance of SrTiO 3 by modifying it with In 2 O 3 remains limited [7][8][9].…”

Photocatalytic water splitting by semiconductors is considered a promising and cost-effective method for achieving sustainable hydrogen production. In this study, a CF/SrTiO3/In2O3 photocatalytic material with a double-layer core–shell structure was developed. The experimental results indicated that the produced CF/SrTiO3/In2O3 composite fiber displayed superior photocatalytic hydrogen production performance, achieving a hydrogen evolution rate of approximately 320.71 μmol/g·h, which is roughly seven times higher than that of the CF/SrTiO3 fiber alone. The enhanced photocatalytic activity of the CF/SrTiO3/In2O3 fiber can be attributed to the heterojunction structure enriched with oxygen vacancies. It was found that these oxygen vacancies created defective states that served as traps for photogenerated electrons, facilitating their migration to the surface defect states and enabling the reduction of H+ in water to produce hydrogen. Furthermore, the synergy between the heterojunction structure and the conductivity of the carbon fiber promoted the generation and migration of photogenerated electrons, reduced the recombination of photogenerated electron–hole pairs, and ultimately improved photocatalytic hydrogen production. This study presents a new approach for designing efficient photocatalysts with surface oxygen vacancies on carbon fibers, providing new insights into the sustainable application of photocatalysts.

“…Dielectric thin films with voltage tunable permittivity have attracted much attention for applications in the electrically tunable microwave capacitor devices such as resonators, phase shifters, filters and antennas [1][2][3][4]. Due to low dielectric loss and large tenability, Bi 1.5 MgNb 1.5 O 7 (BMN) film has been regarded as a promising potential candidate for tunable microwave devices [4,5]. Using Pt or Au as electrodes, high dielectric tunability was achieved by using metal-insulator-metal (MIM) structures.…”

We report a kind of electric field tunable transparent and flexible capacitor with the structure of graphene-Bi 1.5 MgNb 1.5 O 7 (BMN)-graphene. The graphene films with low sheet resistance were grown by chemical vapor deposition. The BMN thin films were fabricated on graphene by using laser molecular beam epitaxy technology. Compared to BMN films grown on Au, the samples on graphene substrates show better quality in terms of crystallinity, surface morphology, leakage current, and loss tangent. By transferring another graphene layer, we fabricated flexible and transparent capacitors with the structure of graphene-BMN-graphene. The capacitors show a large dielectric constant of 113 with high dielectric tunability of~40.7 % at a bias field of 1.0 MV/cm. Also, the capacitor can work stably in the high bending condition with curvature radii as low as 10 mm. This flexible film capacitor has a high optical transparency of~90 % in the visible light region, demonstrating their potential application for a wide range of flexible electronic devices.
