A novel flower-like and holes-rich ZnO nanostructured
catalyst, possessing 6-fold building blocks and wurtzite structure
with [011-0] orientation that shows activity for the hydrogenation
of CO is investigated. The evidence for this activity was shown
2
with a Diffuse Reflectance Infrared Fourier Transform
Spectroscopy (DRIFTS) study. From the DRIFTS analysis it is
known that methanol is formed at atmospheric pressure and
relatively low temperatures with this novel ZnO catalyst. The
photocatalytic decomposition of methylene blue was also studied
using nanostructured ZnO that was modified with Li, Au and Ag.
Results show that Li is detrimental to the photocatalytic activity,
while Au and Ag increase the activity due to the electron transfer
between ZnO and novel nanoparticles.

The world is facing unprecedented challenges, which are
powerful drivers for change in society and economy. The
developments in Sustainable chemistry (SC) are essential to
master these through innovation, while balancing the 3 aspects of
Sustainable Development (SD) (ecologic, economic and societal
dimension). For society these can offer major global market
opportunities for jobs and growth, if research on SC can be
successfully transferred into broadly available innovative products
and processes. In order to be successful academia and industrial
players from the chemical sector and along the value chain have
to work together.
Parameters to measure the progress on SC have to include
molecular work (like on “Green Chemistry”) as well as the
specific uses along the value chain till disposal. Validated
approaches are urgently needed including acceptable screening
criteria as neither raising unwarranted expectations in policy and
the public nor “green washing” by any stakeholder is acceptable
anymore. Life cycle assessment approaches can be useful as a
measuring tool and guiding principle. However it must be
recognized that these complex tools are not easily suited for
communication to the general public and dependent on regional
parameters. At global level it is essential to optimize a variety of
parameters in the direction of SD due to the different framework
conditions. Improved education on sustainability as part of
students and employees curricula is vital. Interested stakeholders
have to find new ways of cooperation like around the EU
Technology and Innovation Platform for Sustainable Chemistry
(SusChem).
The European Chemical Industry has established a coherent
open and cooperative program to tackle these challenges, which
will be presented and discussed.
