“…Stronger PL emission intensity corresponds to more severe electron-hole recombination. 18,[84][85][86][87] Distinctly, BWO displays an intense PL emission peak, signifying its rapid electron-hole recombination rate. Compared with pristine BWO, the CN/BWO heterojunctions manifest remarkable emission quenching, demonstrating the efficient disassociation of charge carriers by the construction of heterojunctions.…”

Bismuth sulfide (Bi2S3) enabled us to transform light signals into electrical signals via the photoelectric effect, which exhibited tremendous prospects on constructing wireless electrical stimulation for accelerating nerve regeneration. However, too rapid recombination of photogenerated electron–hole pairs weakened its photocurrent. Herein, the Bi2S3/Ti3C2T x heterojunction was synthesized by in situ growth of Bi2S3 nanoparticles on Ti3C2T x nanosheets and then mixed with poly-l-lactic acid (PLLA) powder to fabricate the Bi2S3/Ti3C2T x -PLLA conduit. At the heterojunction interfaces, Ti3C2T x with a more positive Fermi energy level could form interfacial potential difference with Bi2S3 to promote electron–hole pair separation. Meanwhile, Ti3C2T x with excellent conductivity could provide channels for photogenerated electron transmission, thus facilitating the generation of the photocurrent. Photoluminescence and electrochemical impedance spectroscopy analysis indicated that electron–hole pair separation and electron transfer were enhanced. As a consequence, under near-infrared light radiation, the output photocurrent of Bi2S3/Ti3C2T x -PLLA was increased from 0.48 to 1.43 μA compared to that of Bi2S3-PLLA. The enhanced photocurrent effectively promoted the differentiation of rat pheochromocytoma (PC12) into functional neurons by upregulating extracellular Ca2+ influx. Therefore, the above results demonstrated that this work provided a new perspective for wireless electrical stimulated nerve regeneration.

“…Bismuth oxychlorides refer to compounds with different ratios of Bi : O : Cl (e.g., BiOCl, Bi 3 O 4 Cl, Bi 12 O 17 Cl 2 , and Bi 24 O 31 Cl 10 ) [15][16][17][18], which has become one of the research hotspots of photocatalytic applications in recent years. Among these compounds, Bi 12 O 17 Cl 2 photocatalyst has aroused great interest of scientists due to its excellent visible light absorption capacity, strong oxidation capacity, and small bandgap energy [19][20][21][22]. Zhang et al prepared a two-dimensional BiOCl/ Bi 12 O 17 Cl 2 heterojunction photocatalyst, which improved the photocatalytic removal efficiency of nitric oxide (NO) [23].…”

We report a heterojunction photocatalyst by coupling CdS with Bi12O17Cl2 via a facile thermal annealing process. Such heterostructure can promote the charge separation between CdS and Bi12O17Cl2, thereby leading to a considerable improvement on the performance for CO2 reduction into valuable CH4 and phenol conversion under visible light exposure. The CdS/Bi12O17Cl2 heterojunction with mass ratio of 1 : 1 (50% CdS/Bi12O17Cl2) shows the highest CH4 production rate (1.28 μmol·h-1·g-1), which is as 9.8 and 5.8 times as the CH4 generation rate of pure Bi12O17Cl2 and CdS (0.13 and 0.22 μmol·h-1·g-1), respectively. Also, the 50% CdS/Bi12O17Cl2 sample shows the highest activity of phenol conversion with a conversion ratio of 92%, which is as 2.2 times and 1.9 times as the conversion ratio of pristine Bi12O17Cl2 (41%) and CdS (48%), respectively. The present study demonstrates the great potential of the CdS/Bi12O17Cl2 heterojunction for efficient charge separation towards increased photocatalytic CH4 production and phenol conversion.
