Through first-principles structure search calculations, we have identified ten hitherto unknown two-dimensional (2D) Janus-wrinkled TMTe monolayers (TM = Ni, Pd, Pt, Co, Rh, Ir, Fe, Ru, Os, and Hf) by screening 3d, 4d, 5d transition metal atoms. These exhibit high stability metallic conductivity. Among the discovered materials, 2D PdTe (ηOER/ORR 0.46/0.22 V) PtTe 0.46/0.32 can demonstrate superior bifunctional catalytic performance for oxygen evolution reduction reactions (OER/ORR), with lower overpotential than state-of-the-art IrO2 OER Pt (111) ORR, respectively. The TM- Te-sides originating from unique Janus configurations play a crucial role in ORR activities, Furthermore, stacking monolayer structures, eight new (TMTe)2 bilayers conductivity be achieved, which possess an internal layer, forming rich electron pool. This effectively improves adsorption activity on some bilayers, including (PdTe)2, (PtTe)2, (RhTe)2, (IrTe)2, transferring more electrons to adsorbed O2 molecule, leading considerably (ηORR 0.16–0.44 V). Moreover, detailed analyses of mechanisms been conducted. intriguing findings offer insights designing low-cost high-performance electrocatalysts reactions, potential replace related noble catalysts used water splitting, fuel cells, metal-air batteries, etc.
