Competing Interests

Development of the titanate photocatalysts used in the study, as well as their adhesion to substrates, was supported by the Laboratory Directed Research and Development (LDRD) program at Sandia National Laboratories. Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed-Martin Company, for the United States Department of Energy under Contract No. DEAC04-94AL85000. This does not alter the authors’ adherence to all the PLOS ONE policies on sharing data and materials. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. Synthesis and application of the catalytic materials is the subject of a provisional patent application assigned serial number 61/577,349.
