The
structural design of multiple functional components could integrate
synergistic effects to enhance the catalytic performance of MoS2-based composites for catalytic applications. Herein, one-dimensional
(1D) Co-MoS2/Pd@NCMTs composites were designed to prepare
Co-doped MoS2/Pd nanosheets (NSs) on N-doped carbon microtubes
(NCMTs) from tubular polypyrrole (PPy) as multifunctional catalysts.
The Co-MoS2/Pd@NCMTs composites integrated the synergistic
effects of Co-doping, a 1D tubular structure, and noble-metal Pd decoration.
Thus, a higher catalytic activity was observed in 4-nitrophenol (4-NP)
reduction and peroxidase-like catalysis than other components, such
as MoS2, MoS2@NCMTs, and Co-MoS2@NCMTs.
Remarkably, the results indicated that the dissolution, diffusion,
and redistribution led to the dissolution of MoO3@ZIF-67
cores and generation of Co-doped MoS2 NSs. Benefiting from
the synergistic effect from these components, Co-MoS2/Pd@NCMTs
were considered as a facile colorimetric sensing platform for detecting
tannic acid. Moreover, outstanding performance was realized in the
reduction of 4-NP with the composites. Thus, we provide a simple synthetic
strategy for simultaneously integrating electronic engineering and
structural advantages to develop an efficient MoS2-based
multifunctional catalyst.
Engineering a tube-like architecture with bimetallic nanoparticles (NPs) has been considered an effective strategy for enhancing catalytic performance. Herein, we report on a simple method for preparing one dimensional (1D)...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
