Bioelectronics are powerful tools for monitoring and stimulating biological and biochemical processes, with applications ranging from neural interface simulation to biosensing. The increasing demand for bioelectronics has greatly promoted the development of new nanomaterials as detection platforms. Recently, owing to their ultrathin structures and excellent physicochemical properties, emerging two‐dimensional (2D) materials have become one of the most researched areas in the fields of bioelectronics and biosensors. In this timely review, the physicochemical structures of the most representative emerging 2D materials and the design of their nanostructures for engineering high‐performance bioelectronic and biosensing devices are presented. We focus on the structural optimization of emerging 2D material‐based composites to achieve better regulation for enhancing the performance of bioelectronics. Subsequently, the recent developments of emerging 2D materials in bioelectronics, such as neural interface simulation, biomolecular/biomarker detection, and skin sensors are discussed thoroughly. Finally, we provide conclusive views on the current challenges and future perspectives on utilizing emerging 2D materials and their composites for bioelectronics and biosensors. This review will offer important guidance in designing and applying emerging 2D materials in bioelectronics, thus further promoting their prospects in a wide biomedical field.

“…In addition to traditional substrate materials, loading noble metal cocatalyst on the surface of PNCs to form novel heterostructure with extraneous surface plasmon resonance has been considered as an effective way to improve visible light absorption and facilitate charge separation. [ 116–118 ] For example, Huang and co‐workers synthesized CsPb(Br 1‐ x Cl x ) 3 ‐Au nano‐heterostructures, which demonstrated a more satisfactory photocatalytic degrade ability that about 71% of Sudan Red III under visible light irradiation than that of pure CsPb(Br 1‐ x Cl x ) 3 NCs.

Perovskite Nanocrystals‐Based Heterostructures: Synthesis Strategies, Interfacial Effects, and Photocatalytic Applications

Solar RRL

Perovskite nanocrystals (PNCs) have recently emerged as a new type of promising photocatalytic semiconductor due to their unique photoelectrochemical properties, including tunable bandgap and crystal structure, entire visible spectral response, and versatile chemical processability. However, under practical circumstance, this type of pure‐phase PNCs photocatalyst demonstrates poor stability, limited light utilization, and high carrier recombination, resulting in low solar power conversion efficiency and inferior catalytic activity. To address these issues, extensive research efforts have been devoted to developing PNCs‐based heterostructures. Thus, a perspective on the development of PNCs‐based heterophotocatalysts is timely. In this Review, the progress of PNCs‐based heterophotocatalysts is presented starting from fundamental properties (i.e., crystal and bandgap structure, photoelectronic properties, etc.) to state‐of‐the‐art applications with a focus on stability improving, dispersion enhancing, and interfacial charge carrier dynamic optimizing. Critical insights are further provided into the existing challenges and prospects for high‐quality PNCs‐based heterostructures in advanced photocatalytic applications.

“…As known, the photocatalytic efficiency is mainly dependent on the following three factors, that is, light absorption, charge separation, and surface activity. Previous studies have revealed that the loading of noble metal cocatalyst on the surface of a photocatalyst can form a heterojunction structure accompanying with the local surface plasmon resonance, which can not only improve the visible light absorption but also facilitate charge separation. In view of this, Zhao et al constructed the Ag‐CsPbBr 3 /C 3 N 4 composites by loading nano‐Ag onto the surface of CsPbBr 3 /C 3 N 4 composite, to degrade 7‐aminocephalosporanic acid (7‐ACA) (a basic skeleton of cephalosporin antibiotics).…”

Inorganic halide perovskite quantum dots (IHPQDs) have recently emerged as a new class of optoelectronic nanomaterials that can outperform the existing hybrid organometallic halide perovskite (OHP), II–VI and III–V groups semiconductor nanocrystals, mainly due to their relatively high stability, excellent photophysical properties, and promising applications in wide‐ranging and diverse fields. In particular, IHPQDs have attracted much recent attention in the field of photoelectrochemistry, with the potential to harness their superb optical and charge transport properties as well as spectacular characteristics of quantum confinement effect for opening up new opportunities in next‐generation photoelectrochemical (PEC) systems. Over the past few years, numerous efforts have been made to design and prepare IHPQD‐based materials for a wide range of applications in photoelectrochemistry, ranging from photocatalytic degradation, photocatalytic CO2 reduction and PEC sensing, to photovoltaic devices. In this review, the recent advances in the development of IHPQD‐based materials are summarized from the standpoint of photoelectrochemistry. The prospects and further developments of IHPQDs in this exciting field are also discussed.
