Editorail: What's in a Name?

"What is the first thing that draws the attention of any reader to look into a scientific paper? Naturally, it is the title. The title is something that stays around for the life of a paper, similar to an inherited name. Given the volume of papers being published in any given discipline in recent years, one can easily miss reading a paper if the article title listed in a journal's table of contents or in database search results fails to draw the attention of a potential reader. Is it not worth an author's time to come up with an effective and attractive title?"

Editorail: Reporting on Heterogeneous Photocatalysis

This editorial written for ACS Applied Materials and Interfaces looks into the best practices for reporting on hetergeneous photocatalysis. It includes tips for making measurements as well as proper reporting of values and things to watch out for in the literature.

Best Practices for Reporting on Heterogeneous Photocatalysis

Heterogeneous photocatalysis is of broad interest in materials chemistry and materials science, particularly with the rapid growth of research attention being directed toward energy-related applications, pollution mitigation, and other related areas of environmental impact.(1) A literature survey reveals more than 9000 papers with the word photocatalyst or photocatalysis in the title published during the last ten years (Source: Web of Science, July 3, 2014), with the number of papers published each year increasing significantly since 2005. The materials and physical chemistry journals of the American Chemical Society receive a significant number of papers in the area of photocatalysis.

Catalytic Reduction of CO2 with TiO2

Read the latest paper from the Kamat Lab!

The Origin of Catalytic Effect in the Reduction of CO2 at Nanostructured TiO2 Films

The Origin of Catalytic Effect in the Reduction of CO2 at Nanostructured TiO2 Films

Abstract: Electrocatalytic activity of mesoscopic TiO2 films towards the reduction of CO2 is probed by depositing a nanostructured film on a glassy carbon electrode. The one-electron reduction of CO2 in acetonitrile seen at an onset potential of -1.1 V (vs. NHE) is ~0.5 V lower than the one observed with a glassy carbon electrode. The electrocatalytic role of TiO2 is elucidated through spectroelectrochemistry and product analysis. Ti3+ species formed when TiO2 film is subjected to negative potentials have been identified as active reduction sites. Binding of CO2 to catalytically active Ti3+ followed by the electron transfer facilitates the initial one-electron reduction process. Methanol was the primary product when the reduction was carried out in wet acetonitrile.

PhysOrg: Band Filling in Perovskite

Band filling with free charge carriers in organometal halide perovskites

PhysOrg: A new paper by University of Notre Dame researchers describes their investigations of the fundamental optical properties of a new class of semiconducting materials known as organic-inorganic "hybrid" perovskites.

The research was conducted at the Notre Dame Radiation Laboratory by Joseph Manser, a doctoral student in chemical and biomolecular engineering, under the direction of Prashant Kamat, Rev. John A. Zahm Professor of Science. The findings appear in a paper in the August 10 edition of the journal Nature Photonics.
