Update 4: The Dark Side of Photochemistry

Photochem Test Tubes

This week I continued my photochemistry experiments from last week, but this time I used different materials for the sacrificial donor. Right now, I am experimenting with varying┬áconcentrations of a substance found in natural waters. Unfortunately, gas chromatography analysis showed little to no hydrogen production. Why is this the case? Natural water samples have been […]

Update 3: Fun with Photochem!

As I wrote about in an earlier post, the focus of my summer research is to determine a natural source of hydrated electrons that will generate hydrogen in a photocatalytic system. Thus, I will be performing many photochemistry experiments. This week I started to learn this procedure and ran a couple of experiments with materials […]

Update 2: FTIR and the Art of Preparing TiO2 Slides

This week was dedicated to gathering data on an electrocatalyst we had recently synthesized. I learned how to use FTIR (Fourier Transform Infrared Spectroscopy) to take scans of the iron complex. First, I ran a background scan of potassium bromide (KBr), which we use as a carrier for the sample. Then, I ran a sample […]
