Grantham Scholar Benedict Smith’s project looks at making graphene based sensors more selective.
Making graphene-based sensors more selective for phosphate species by the addition of 2D met organic frameworks which functionalise the surface and have changeable affinity for a variety of analytes. This is applicable to farming, where the distribution and soil retention of fertilisers should be monitored to prevent overspreading (wasteful, costly, environmentally damaging). An electrochemical sensor is the target device to allow remote, sub-field measurement over a large area.

The Grantham Centre at COP. Every year, we send Grantham Scholars to COP as official observers for the University of Sheffield. Doing so gives our people an opportunity to see how global climate change policy is made – or not – and to meet other sustainability experts. In 2022, Benedict was one of the group who went to Egypt for COP27.
Free sustainability webinars. Benedict was part of a group who organised the Rewilding: Plant it and They Will Come webinar. Created as part of our ongoing public engagement, it is on of a playlist of Grantham Scholar webinars available on YouTube.
You can find Benedict on Twitter.
