Summary Nanogenerators is the growing technology that facilitates self‐powered systems, sensors, and flexible and portable electronics in the thriving era of internet of things (IoT). Since the first invention of the triboelectric nanogenerators (TENGs) in 2012, it has become one of the most important inventions in energy harvesting technologies. In this paper, a brief review on the recent progress of energy harvesting research based on TENGs technology is discussed. Basic working modes of the TENG are discussed in detail and the general procedure to synthesize, measure, and characterize a nanogenerator is presented in a direct structure. The triboelectric material choices are extremely important for TENGs since the triboelectric effects of the materials are fundamental for TENGs. The materials used as triboelectric layers are varied from polymers, metals, and inorganic materials with the commonly used materials are dielectric polymers such as PTFE, PVDF, PDMS, nylon, and Kapton. Recently, two‐dimensional (2D) materials have been widely reported as candidate materials for TENGs. Graphene, the most attractive 2D materials exhibits an excellent electrical property, great flexibility, and a high surface‐to‐volume ratio. Owing to the very low thickness of the atomic unit, a stacking graphene structure can be also made to form a very thin and miniature TENGs device. The major applications of the graphene as active materials for TENGs as a sustainable energy harvester are presented, following which structural designs and materials optimization for output performance improvement of the graphene‐based TENGs are summarized. Finally, the future directions and perspectives of the graphene‐based TENGs are outlined. The graphene‐based TENGs is not only a sustainable micro‐power source for small devices, but also serves as a potential macro‐scale generator of power from blue energy in the future.

Heteroatom doping can endow MXenes with various new or improved electromagnetic, physicochemical, optical, and structural properties. This greatly extends the arsenal of MXenes materials and their potential for a spectrum of applications. This article comprehensively and critically discusses the syntheses, properties, and emerging applications of the growing family of heteroatom‐doped MXenes materials. First, the doping strategies, synthesis methods, and theoretical simulations of high‐performance MXenes materials are summarized. In order to achieve high‐performance MXenes materials, the mechanism of atomic element doping from three aspects of lattice optimization, functional substitution, and interface modification is analyzed and summarized, aiming to provide clues for developing new and controllable synthetic routes. The mechanisms underlying their advantageous uses for energy storage, catalysis, sensors, environmental purification and biomedicine are highlighted. Finally, future opportunities and challenges for the study and application of multifunctional high‐performance MXenes are presented. This work could open up new prospects for the development of high‐performance MXenes.

Triboelectric nanogenerator (TENG)-based display techniques are promising in converting kinetic energy into light signals for optical communications. However, the instantaneous TENG current usually generates transient light, leading to incomplete information. Hence, a self-powered phosphorescence display (SPD) system is proposed to realize complete information display. Ultralong organic phosphorescence (UOP) combined with an elastomer is applied to contrive a delayed luminescent array, and a TENG in a slant grating electrode of 45°is fabricated to generate electricity in latitudinal and longitudinal trajectories. The assembled SPD system can provide ultralong phosphorescence over 2.5 s, about 10 times longer than the original LED. A luminescent array is fabricated to demonstrate the delayed display of the SPD system, where the patterned trajectory of the TENG is reproduced as a delayed display that can avoid missing information. This SPD system is anticipated to improve applications of UOP materials in displays and to broaden applications of TENG in self-powered display and visualized tracking.
