“…11,19 As an important derivative of graphene, graphene oxide (GO) possesses a large amount of oxygen-containing-groups (OCGs), which makes it easy to be modified, either chemically or physically. [35][36][37] In particular, photoreduction of GO by lasers can simply engineer both its physical and chemical properties locally and tunably. 11,17,38 The rich OCGs also make GO hydrophilic and easy to interact with water molecules by forming hydrogen bonds.…”

The micro‐scale energy storage devices (MESDs) have experienced significant revolutions driven by developments in micro‐supercapacitors (MSCs) and micro‐batteries (MBs). This review summarizes the advancements of MSC and MB architecture, highlighting the electrode–electrolyte designs and the emergence of alkali metal ions aqueous batteries. The performance and synthesis of carbon quantum dots (CQDs), graphene quantum dots (GQDs), and their synergistic effects for energy storage applications are investigated. The focus is on integrating CQDs/GQDs into the MESDs for enhanced performance. The development of compositing CQD/GQD with other materials, reveals their capacitive and pseudocapacitive performance, extending the MESDs’ possibilities. Moreover, this review systematically covers various fabrication techniques from photolithography to printing techniques. The merits and practicality of each technique for fabricating MSCs and MBs are assessed. Electrochemical performance evaluation, capacitance enhancement, charge–discharge kinetics, and stability assessments are presented to demonstrate the efficiency of MESDs with practical applications. Despite significant progress, challenges remain, particularly in the scalability of fabrication and understanding long‐term stability. Nevertheless, the prospects are promising, with avenues in synthesis, fabrication, and electrochemical performance evaluation, which lead to a paradigm shift in MESDs. This review offers a broad perspective, combining innovations across diverse domains and directing the frontline of microelectronics.

Triboelectric nanogenerators are promising green electrocatalytic alternative energy sources; however, their low current density renders practical applications challenging. Herein, a self‐generating electricity mode based on a droplet friction strategy that significantly mitigates membrane fouling while facilitating the contact of oxidizing substances and sulfamethoxazole within the nanoconfined spaces of 2D conductive catalytic membranes is proposed, which are elaborately designed via the co‐assembly of CoFeMoOOH and MXene laminates. In the confined domain space of the membrane, triboelectric pulses resulted in a 267% (1800 to 4800 min−1) enhancement of the degradation rate constant of sulfamethoxazole, which is significantly higher than the 17% (0.35 to 0.41 min−1) for the suspension system. In situ filtration and kinetic modeling revealed that the pulsed electrical signal generated by the permeate promoted molecular polarization and longitudinal mass transfer within the confined domain space. The alteration in the adsorption‐desorption behavior of solvent/solute molecules between the confined domain layers leads to the migration of water molecules and pollutants in opposite directions, facilitating positive catalytic reactions and fouling inhibition. The proposed self‐generating pulsed electricity‐assisted nanoconfined catalysis offers a powerful tool for efficiently harnessing environmental micro‐energy for the green upgrading of water treatment processes.
