Hierarchically Converged Defect Engineering with 2-Dimensional Black Phosphorus/MXene Sequence for Sensitive Photoelectrochemical-Electrostatic Sensors.

ABSTRACT: The function-integrated sensors have harvested increasingly vital across diverse applications, especially in the field of smart wearables, yet optimizing the synergy between electrostatic and light signals in photoelectrochemical (PEC) systems remains a critical challenge. Here, we fabricate a hierarchical ZnO/Bi₂O₃/BiOCl/black phosphorus (BP)/MXene (Ti₃C₂T _x ) heterostructure and develop a PEC sensor tailored for electrostatic coupling and surface electromyography (sEMG) detection. Sequential integration of 2-dimensional (2D) BP and Ti₃C₂T _x precisely repairs defects in the 3D ZnO/Bi₂O₃/BiOCl framework, enhancing electrode contact area and forming multidimensional he
