Abstract

Creating a new chemical ecosystem based on platform chemicals derived from waste biomass has significant challenges: catalysts need to be able to convert these highly functionalized molecules to sp...

Highlights

To expedite the transition from a chemical ecosystem based on petroleum to one based on sustainable bioderived platform chemicals requires a concerted effort: catalysts need to (i) be highly active under mild conditions, (ii) be atom efficient and achieve a high selectivity to a desired product, (iii) maintain performance over many cycles, and (iv) be economical by not relying on large amounts of scarce and expensive metals
Pd nanoparticles were supported on TiO2 (P25, 50 m2 g−1) and NiO through an established sol-immobilization method with a loading of 1 wt %
The metal loading was confirmed by atomic absorption spectroscopy (AAS)

Summary

■ INTRODUCTION

To expedite the transition from a chemical ecosystem based on petroleum to one based on sustainable bioderived platform chemicals requires a concerted effort: catalysts need to (i) be highly active under mild conditions, (ii) be atom efficient and achieve a high selectivity to a desired product, (iii) maintain performance over many cycles, and (iv) be economical by not relying on large amounts of scarce and expensive metals. These objectives necessitate detailed catalytic studies that probe the performance on an atomistic level and are able to describe how specific materials promote these complex transformations.
