ABSTRACT
Catalysis, as a key and enabling technology, plays an increasingly important role in fields ranging from
energy, environment and agriculture to health care. Rational design and synthesis of highly efficient
catalysts has become the ultimate goal of catalysis research. Thanks to the rapid development of
nanoscience and nanotechnology, and in particular a theoretical understanding of the tuning of electronic
structure in nanoscale systems, this element of design is becoming possible via precise control of
nanoparticles’ composition, morphology, structure and electronic states. At the same time, it is important to
develop tools for in situ characterization of nanocatalysts under realistic reaction conditions, and for
monitoring the dynamics of catalysis with high spatial, temporal and energy resolution. In this review, we
discuss confinement effects in nanocatalysis, a concept that our group has put forward and developed over
several years. Taking the confined catalytic systems of carbon nanotubes, metal-confined nano-oxides and
2D layered nanocatalysts as examples, we summarize and analyze the fundamental concepts, the research
methods and some of the key scientific issues involved in nanocatalysis. Moreover, we present a perspective
on the challenges and opportunities in future research on nanocatalysis from the aspects of: (1) controlled
synthesis of nanocatalysts and rational design of catalytically active centers; (2) in situ characterization of
nanocatalysts and dynamics of catalytic processes; (3) computational chemistry with a complexity
approximating that of experiments; and (4) scale-up and commercialization of nanocatalysts.

Keywords: nanocatalysis, confinement, carbon nanotubes, graphene, 2D materials, inverse catalysts,
computational chemistry, in situ characterization
