Edge-rich MoS2 nanosheets anchored on layered Ti3C2 MXene for highly efficient and rapid catalytic reduction of 4-nitrophenol and methylene blue

Exploring the catalytic activity of Nb4C3Tx MXene towards the degradation of nitro compounds and organic dyes by in situ decoration of palladium nanoparticles

“…The time dependent absorption spectra showed that MB reduced rapidly to Leuco MB (LMB) in just 75 s, which was verified by the disappearance of the peak. 45 Similarly, the Nb 4 C 3 T x @Pd5 catalyst was also able to completely reduce MO within 120 s. The UV-vis spectrum of MO was observed at 464 nm, which decreases rapidly with time and the The ln(c t /c 0 ) vs. reaction time plot for Nb 4 C 3 T x @Pd5 catalyst towards the reduction of MB and MO are given in Fig. 7(b and d), respectively.…”

“…Recently, MoS 2 nanosheets anchored on Ti 3 C 2 T x were synthesized and their catalytic activity towards the catalytic reduction of 4-NP and MB was evaluated. 37 This MoS 2 -Ti 3 C 2 T x composite exhibited enhanced catalytic activity with rate constants 0.61 min À1 and 0.779 min À1 for the degradation of 4-NP and MB, respectively.…”

A novel ReS2–Nb2CTx composite as a sensing platform for ultrasensitive and selective electrochemical detection of dipyramidole from human serum

“…Different MXene-based composite materials have been introduced to enhance the electrochemical properties of MXenes [23][24][25]. Two-dimensional transition metal dichalcogenides (TMDCs) are gaining importance due to their layered structure and ability to form composite with MXene [26]. TMDCs possess a lamellar structure, highly exposed edge sites that imparts a catalytic nature towards the electrochemical sensing [27].…”

In Situ Implantation of Bi2S3 Nanorods into Porous Quasi-Bi-MOF Architectures: Enabling Synergistic Dissociation of Borohydride for an Efficient and Fast Catalytic Reduction of 4-Nitrophenol

“…Unlike magnetic metals such as iron, cobalt, and nickel, which are prone to aggregation, nonmagnetic transition metals are more suitable for stable and long-term catalysis. − Among them, bismuth (Bi)-based compounds have emerged as promising active materials for a variety of catalysis applications due to their earth abundance, low cost, and less toxicity. − Several bismuth-based catalysts have been recently implemented for the catalytic reduction conversion of 4-NP. The semimetallic Bi nanoparticles were first demonstrated as a potential candidate for catalytic 4-NP reduction with a normalized rate constant of 27.51 s –1 g –1 ; however, their easy aggregation remarkably deteriorated the catalytic activity .…”
