In particular, the dynamic evolution of support at microscopic scale may play a critical role in heterogeneous catalysis, however, identifying the in situ structural change of support under working condition with atomic precision and revealing its role in catalysis is still a grand challenge. Herein, we visually capture the surface lattice expansion of WO\n                    <jats:sub>3\u2212x<\/jats:sub>\n                    support in Pt\u2013WO\n                    <jats:sub>3\u2212x<\/jats:sub>\n                    catalyst induced by NO in the exemplified reduction of NO with H\n                    <jats:sub>2<\/jats:sub>\n                    using in situ transmission electron microscopy and first reveal its important role in enhancing catalysis. We find that NO can adsorb on the oxygen vacancy sites of WO\n                    <jats:sub>3\u2212x<\/jats:sub>\n                    and favorably induce the reversible stretching of W\u2013O\u2013W bonds during the reaction, which can reduce the adsorption energy of NO on Pt\n                    <jats:sub>4<\/jats:sub>\n                    centers and the energy barrier of the rate-determining step. The comprehensive studies reveal that lattice expansion of WO\n                    <jats:sub>3\u2212x<\/jats:sub>\n                    support can tune the catalytic performance of Pt\u2013WO\n                    <jats:sub>3\u2212x<\/jats:sub>\n                    catalyst, leading to 20% catalytic activity enhancement for the exemplified reduction of NO with H\n                    <jats:sub>2<\/jats:sub>\n                    .
