Recently, 2D semiconductor-based heterojunctions emerge as a focal point of intensive research owing to their unique properties, including efficient charge separation and large interface areas. Herein, Ni or Co-doped black phosphorus/molybdenum disulfide (BP/MoS2-Y (Y: Ni, Co)) heterojunctions fabricate for photocatalytic H2 evolution and electro-chemical nitrite sensor. Compared to the BP/MoS2, the BP/MoS2-Ni and BP/MoS2-Co exhibit enhanced H2 performance, as 6.4139 mmol h-1 g-1 and 7.4282 mmol h-1 g-1, respectively, in the presence of Eosin-Y (l >= 420 nm). Furthermore, BP/MoS2-Co applies as an electrocatalyst on a GCE for the electrochemical detection of nitrite. To optimize the nitrite sensing performance of BP/MoS2-Co, the effect of the pH, amount of material, scan rates, and other conditions study in detail. The BP/MoS2-Co displays a linear response within the range of 100-2000 mM with a detection limit of 4.1 mM for DPV. This work can offer an opportunity for hydrogen systems as well as electrochemical sensor applications. (c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
