Synthesis of ammonium decavanadate, and analysis via IR, UV-Vis and quantitative titration. Time: 1.5 lab periods
Purpose
The purpose of this lab experiment is to expose students to the synthesis of a colored POM, and to connect the use of standard analytical techniques to this new type of compound. It introduces the use of IR spectroscopy of inorganic materials.

Determining the reactive intermediates in metalloenzymes is a very involved task, and requires drawing from many different spectroscopies and physical methods. The facile activation and oxidation of methane to produce methanol is one of the "holy grails" of inorganic chemistry. Strategies exist within materials science and organometallic chemistry to activate methane, but using the enzyme methane monooxygenase, nature is able to carry out this difficult reaction at ambient temperatures and pressures (and in water, too!).
These slides provide a brief introduction to the concept of electrocatalysis using the glyoximato cobalt catalysts for hydrogen production recently examined by Peters, Gray, and others. They provide a suitable introduction to the topic for students interested in reading the primary literature on these topics.
This in-class activity introduces students to copper-mediated cross coupling reactions. In the literature, many cross coupling reactions are often discussed using palladium as a catalyst, not copper. In my laboratory, we are synthesizing 7-azaindole-based ligands for the development of potential anti-tumor platinum(II) complexes. In addition, I use one of my own publications to demonstrate an application of this synthetic strategy. The students calculate the actual turnover number (TON) and turnover frequency (TOF) for the copper catalyst.
This is a great web resource for all types of nano materials. There are lesson plans, demos, activites, labs and lots of background information. It is very easy to navigate and there are videos of the labs so you can see each step - very useful when doing a type of synthesis or technique new to you.
This learning object was developed at the 2012 NSF sponsored cCWCS VIPEr workshop at UNC-CH where we were fortunate to hear Jillian Dempsey present this research that has appeal to students. This work focuses on an exciting and promising strategy to develop new technology to support a solar energy economy. This literature discussion leads students through a current application in the field of electrocatalysis.
For many years I have resisted using clickers, mainly because at our university there is no standard universal clicker. I wanted to keep student costs as low as possible but also desired the type of live feedback during a lecture that clicker questions can provide. In both my general chem. (200-300 students) and upper division courses (50-75 students), I now pass out 4 or 5 colored notecards on the first day of class and make sure everyone has one of each color.
This activity is meant to teach students about the types of homogeneous transition metal C-H bond functionalization catalysts. Before class, the students will read a short discussion of inner- and outer-sphere C-H bond functionalization catalysts. Then they will use their knowledge of transition metal oxidation states and ligands in order to assess whether a variety of catalysts react via inner- or outer-sphere pathways.
This set of experiments provides an introduction to simple inorganic synthesis and qualitative analysis of inorganic pigments. I have taught this series of experiments in my first semester junior level inorganic class for the past 5 years. In part 1, students synthesize five inorganic pigments. Part 2 involves identifying an unknown inorganic white pigment by chemical and physical tests. These
