Abstract: A catalyst comprises gold particles and titanium-containing particles. The catalyst comprises gold particles that are within at least 15 nm of at least one titanium-containing particle. The gold particles have an average diameter of less than 15 nm and a standard deviation of +/-5 nm. A method for preparing methyl methacrylate from methacrolein and methanol using the catalyst is also disclosed.
