Theoretical studies with simplified model systems and ensemble experimental measurements have shown that molecular transport and chemical reactions in nanoconfined environments are largely different compared to those in bulk solution. Here we design a well-defined platform with catalytic reaction centers confined in the end of nanopores with controlled lengths to study the <i>in situ</i> dynamic behavior of molecular dynamics and catalytic processes under nanoconfinement at the single-molecule and single-particle level. Variable single molecular mass transport behavior reveals the heterogeneity of the confined environment in the nanopores. The combination of the unique model nanomaterial and the single-molecule imaging technique paves the way to understand the fundamental nanoconfinement effects for catalysis and separations.
