Catalysis is one of the most important areas of process and synthetic chemistry. In view of the vast range of applications, there has been extensive research into making catalysts and catalytic reactions more economical and environmentally friendly. One aspect of this is developing catalysts which can be recycled and reused over and over again with minimal effort. This can be particularly important when considering the viability of a process for industrial development, as catalysts are often expensive and so need to be recovered wherever possible in order to keep down costs.
Green Chemistry provides an excellent forum for such work and below is a selection of the cutting edge research we have published in this area over the last couple of years. These articles have been made free to access until the 27th February 2012, so make the most of this and take a look…
