In the cover picture, we adapt
the ideal from "Journey to the West," one of Chinese four literary
classics. The ancient Chinese mythical character, Monkey King, holds a treasure
in his hand, which represents the catalysts with well-defined interface. CO2 is blown out from the mouth of Monkey King, then goes through the catalyst
interface, and finally is converted into high value-added chemicals like CH4,
CH3OH and CO. This well describes the focus of our paper titled “Progress
and Understanding on Catalysts with Well-defined Interface for Boosting CO2 Conversion”.

ABSTRACT
The noble metal rhodium
(Rh) nanostructures have wide applications in catalysis and electrocatalysis.
In this work, a series of RhNi alloy nanostructures with different Rh/Ni atomic
ratios can be synthesized by one-step wet chemical method. By adjusting RhIII/NiII feed ratio, high-quality one-dimensional Rh1Ni1 alloy nanodendrite assemblies (Rh1Ni1-NDs-As) can be
synthesized selectively. Electrochemical measurements show that the
introduction of Ni can enhance the electroactivity of Rh nanomaterials for
methanol oxidation reaction (MOR) in alkaline media. For potential practical
application, Rh1Ni1-NDs-As reveals improved
electroactivity and durability for MOR compared to commercial Rh nanoparticle
due to the particular morphology, Ni-doping, high electrochemical active area,
and excellent anti-poison ability. Considering the facial synthesis and high
electroactivity/durability, Rh1Ni1-NDs-As may be
promising anode catalysts in direct methanol fuel cells.
