Selective oxidation of methanol to methyl formate on catalysts of Au–Ag alloy nanoparticles supported on titania under UV irradiation

Abstract

Au–Ag alloy nanoparticles on titania exhibit superior photocatalytic performance in selective oxidation of methanol to methyl formate.

Modular Design of Advanced Catalytic Materials Using Hybrid Organic–Inorganic Raspberry Particles

“…The size, morphology, and composition of the incorporated NPs can be modified in a controlled way using postmodification techniques . The NPs can be further grown via liquid phase reactions, ALD, or chemical vapor deposition (CVD) to produce larger particles of monometallic or multimetallic composition with a core–shell or homogeneous structure (Figure B). This is achieved when the growth conditions are chosen such that the rate of metal deposition on the NP exceeds its deposition on the background matrix material.…”

Highly efficient hydrogenation of carbon dioxide to methyl formate over supported gold catalysts

“…8,9 Currently, MF is produced by carbonylation of methanol with CO or by methanol dehydrogenation. 10 Synthesis of MF from CO 2 , H 2 and methanol, which is shown in Equation…”

Photocatalytic hydrogen production by reforming of methanol using Au/TiO2, Ag/TiO2 and Au-Ag/TiO2 catalysts

“…[7][8][9][10][11] Silver based nanoparticles have also received extensive consideration due to their use in a range of potential applications, such as microelectronics, sensing and catalysis. [12][13][14][15][16][17] This paper continues our work on photocatalytic titania 12-21 but reports on the incorporation of nanoparticles (supported Au and Au-Ag nanoparticles) produced by the sol immobilization method. With this methodology, the synthesis of gold based nanoparticles with particle diameters below 10 nm with controlled morphology (random alloy or core-shell structures) is achievable.…”
