MXenes are an emerging class of two-dimensional transition metal carbides and nitrides with metallic conductivity and hydrophilic surfaces. The discovery of MXenes has opened new possibilities for developing advanced hybrid composites for energy storage and conversion applications. This review summarizes recent advances in developing MXene-based hybrid composites, including their synthesis, characterization, and electrochemical performance. The heterostructure of MXenes with nanocarbons, metal oxides, polymers, and other nanomaterials can overcome the limitations of pristine MXenes and lead to enhanced lithium/sodium-ion storage, pseudocapacitive performance, and electrocatalytic activity. Various fabrication techniques have been employed to synthesize MXene composites with controlled nanostructures, morphology, and interfacial properties. Characterization by microscopy, spectroscopy, and electrochemical methods has shed light on structure-property relationships in these materials. As electrode materials, properly designed MXene hybrids have achieved high specific capacity, excellent rate capability, and long-term stability. The review also discusses strategies for further improving MXene composite energy storage performance, as well as emerging applications such as thermoelectrics and photocatalysis. Continued research to understand interfacial effects and optimize MXene heterostructures holds promise for developing next-generation energy storage technologies.

Increased environmental pollution is becoming one of the greatest problem the world is facing nowadays causing irreparable damage to the earth. Because of their novel and tunable physicochemical properties, nano materials have attracted great attention among researchers as promising materials to combat environmental challenges. Developing nanotechnology have triggered a great deal of interest in these structures for pollution monitoring and treatment, enabling new technologies for identifying and addressing environmental problems. Even though achieving environmental pollution control is a challenging task using conventional materials, revolutionary progress has been observed with the advancements in nanotechnology, showing that precisely modified nano materials can be used for purposes such as treatment of polluted atmosphere, industrial and domestic wastewater, natural water, and soil. In this paper we review and discuss the environmental applications of nano materials as nano sensors employed for combating atmospheric and aquatic pollution. Keywords: enviro

The photocatalytic activity and oxygen evolution reaction (OER) of MoS2 and silk graphene (silk G) composite synthesized using supercritical fluids and chemical vapor deposition (CVD) methods were investigated for their potential application in photocatalysis. This material was subjected to characterize by XRD, TEM, SEM and FTIR techniques to demonstrate that MoS2/silk G composite still existed in the supercritical fluids methods obtained MoS2 & MoS2/silk G. The optical features of MoS2 was improved by introduction of silk G, which inturn caused shift in band gap from 1.65 to 1.85 eV. Within visible region, creation of high electron-hole pairs is possible by adequate band gap modifications. The fast movement of photo-induced charge carrier can be enhanced by silk G as they decrease the recombination activity. Additionally, the MoS2/silk G shows high oxygen evolution reaction with low Tafel slope of 157.2 mV dec-1 and low overpotential of 603 mV at a current density of 10 mA cm-2. The present study signifies that with addition of silk G in the MoS2 host improved the photocatalytic activity by 13% and electrocatalytic activity by nearly 5% compared to bare MoS2 nanoparticles.
