Abstract Hydrogen (H 2 ) is mainly produced using steam methane reforming, electrolysis, and gasification, which require external energy special catalysts. A new catalyst by combining MoS nanoflowers (NFs) with metal carbide/nitride nanosheets (Mo CTx MXene) to create a nanosheet bending moment. The @Mo CT x heterostructures achieve production rate of 1164.8 µmol g −1 h under an application mechanical force, 4.01 3.06 times higher than Mo alone, due enhanced charge transfer from 's piezoelectricity conductivity. This study introduces pioneering methodology that harnesses gravitational as continuous simulated peristaltic pump, drive the piezocatalytic hydrogen evolution reaction (HER), achieving notable 454.1 over 24 hours demonstrating sustained capability for generation. theoretical calculation results validate piezoelectric potential in water‐flow‐pressure triggered HER systems. system, assuming powered Hoover Dam, will produce 290.9 kmoles per ton daily, equivalent utilizing 19 150 kWh electrocatalytic system. gravity‐driven water flow piezocatalysts H generation demonstrates superior efficiency eliminating common thermal conversion losses, marking significant breakthrough sustainable technologies.

Abstract Integration of triboelectric nanogenerators (TENGs) with water splitting offers a promising approach for generating green hydrogen from mechanical energy. However, the development efficient TENGs is challenged by significant losses. To enhance sustainable energy harvesting, it crucial to minimize these losses and improve tribo‐polarities. Recent advancements in incorporating conductive fillers have proven effective improving performance. In this study, new class bifunctional amino surface‐modified graphene oxide (MGO) synthesized graphite powder introduced. The MGO filler enhances positive polarity polymer through groups while reducing loss due inherent conductivity graphene. Incorporating 1.5 wt.% into silk electrospun membranes (1.5SMGO) boosted surface positivity +695 +1905 V, surpassing unmodified (GO) (+1220 V), highlighting impact modification. resulting TENG 1.5SMGO exhibits an open circuit voltage 1135 V current density 11.76 mA m − 2 , demonstrating its effectiveness as harvester low‐power electronics. Additionally, proposed can serve source water‐splitting, enabling production. Thus, MGO‐based holds potential self‐powered wearable electronics water‐splitting applications.
