TLDR
The slow pace of hazardous waste remediation at military installations around the world is causing a serious delay in conversion of many of these facilities to civilian uses as discussed by the authors, which is a serious problem.
Abstract
The civilian, commercial, and defense sectors of most advanced industrialized nations are faced with a tremendous set of environmental problems related to the remediation of hazardous wastes, contaminated groundwaters, and the control of toxic air contaminants. For example, the slow pace of hazardous waste remediation at military installations around the world is causing a serious delay in conversion of many of these facilities to civilian uses. Over the last 10 years problems related to hazardous waste remediation have emerged as a high national and international priority.

Photocorrosion Suppression of ZnO Nanoparticles via Hybridization with Graphite-like Carbon and Enhanced Photocatalytic Activity

TL;DR: In this paper, surface hybridization of ZnO with graphite-like carbon layers was proposed to suppress the photocorrosion of nanoparticles, and as-prepared samples exhibited high activity even after 720 h of photocatalysis reaction.

Hexagonal-close-packed, hierarchical amorphous TiO2 nanocolumn arrays: transferability, enhanced photocatalytic activity, and superamphiphilicity without UV irradiation.

TL;DR: A hexagonal-close-packed, hierarchical amorphous TiO2 nanocolumn array was fabricated by pulsed laser deposition (PLD) using a PS colloidal monolayer as a template under a high pressure (6.7 Pa) of background oxygen gas, suggesting that the surface area of theTiO2 is preferable to its crystal structure for enhancing photocatalytic activity.

Photocatalytic properties of gold/gold ion-modified titanium dioxide for wastewater treatment

TL;DR: In this article, a comprehensive study of gold ion-doped TiO 2 and gold-deposited TiO2 was carried out by measuring the photo-activity, X-ray diffraction (XRD) spectra, photoluminescence (PL) spectras, and Xray photo-electron spectra (XPS) of gold, oxygen and titanium.
